Need help with a Engineering statics problem?
There is a problem somewhere. If you look at the hoist as a rigid body the two vertical reaction at the base must sum to 1200 LBS (you can't react more load than is applied). The key is to know the location of the engine center of gravity relative to the hoist supports on the base. Then it is just a matter of summing moments about one of the base supports. Free bodying each individual piece gets a little tricky because it appears you can carry moment across the joint at "D". I disagree with the axial force you show in member "AD". I get a tensile axial force in "AD" (at point "A") of 4704 LBS (4286 / cos 24.33 degrees). I agree with the 5486 LB compression load in what appears to be a shock absorber at "B".
Engineering Statics Help?
I was wondering if anyone knows of a good web page to help learn engineering statics. My current text book is miserable at explaining anything. I currently am using Engineering Mechanics Statics & Dynamics, Fifth Edition by Bedford and Fowler. Any help would be greatly appreciated.
Engineering Statics.?
Is it me or do a lot of people struggle in this course? I'm taking it at a university. I want to major in Civil Engineering, but I fear I am doing very badly in my Statics class. There will be a curve, but I believe I am doing so badly that even with being graded on a curve I will still have a low grade. Unfortunately, I think I am going to be retaking Statics in the spring at my university. I also have to take a course in Dynamics and another course in Mechanics of Materials. Is struggling in Statics an indication that I will probably not succeed in Civil Engineering? I felt like I understood what was going on in lecture and even what the textbook talks about, but the textbook problems seem incredibly difficult. I struggle a lot when it comes to figuring out how to start a problem. We are using the Engineering Mechanics: Statics 5th Edition by Bedford and Fowler. There is also no student solutions manual available for this textbook. The TA's in my class are really harsh graders. I was hoping that because of the difficulty in the problems that there would be some leniency in grading, but this is not the case. I won't be applying to my university's College of Engineering until June for the fall quarter. I am worried that a bad grade in Statics and the fact that I retook it next quarter in spring will look bad to admissions. Do a lot of people struggle in this course? I do not want to give up on my dream of becoming an engineering major just because of this one class. Any feedback or advice would be greatly appreciated. Thank you for reading.
Engineering Statics Help?
A 20kg flowerpot is suspended from three wires and supported by hooks B and C. Determine the tension in AB and AC. I don't exactly have a diagram but the horizontal length from B to C is 4m(l3), length from A to C is 3.5m(l1), and the length from A to B is 2m(l2). The vertical length from B to C is 0.5m(l4). For this problem, I already have the equations -Taccos(phi)+Tabcos(theta)=0 ; Tacsin(phi)+Tabsin(theta) - Mg = 0; l1cos(phi) + l2cos(theta)= l3; l1sin(phi) = l2sin(theta) + l4 Normally, I would be able to solve these equations with the given angles, but It's not given, so if anyone can solve these equations with the steps, that would be amazing. thanks
Engineering Statics Problem- PLEASE HELP!?
If each wire can sustain a maximum tension of 140 before it fails, determine the greatest weight of the chandelier the wires will support in the position shown. The figure is through this link: http://session.masteringengineering.com/problemAsset/1521353/3/Hibbler.ch3.p66.jpg I tried the problem several times using the ( r/ sqrt ( r^2 + h^2) ) for the coefficient of the forces on x and y ( when you take sum of forces on x and y) and the ( h/ sqrt ( r^2 + h^2) ) for the coefficient of the forces on the z ( when you take sum of forces on z). I got to a final answer of 220 lbs but it kept saying its wrong. I tried the problem several times and I still got the same answer. Can you please show me how to work this problem? I have a quiz this afternoon and I need to know how to solve these.
Mechanical Engineering...... what is statics?
the analysis of rigid bodies in static equilibrium. static equilibrium means its not moving. for example, the force of your chair acting on the floor and the reaction force of the floor acting on the chair. the second part of the course should be dynamics. which is the analysis of bodies in dynamic equilibrium (moving bodies). not difficult. just practice, practice, and practice.
STATICS PROBLEM! ENGINEERING?
the resultant of a certain system of forces has the X and Y components shown in Fig. 220. Determine the components of this resultant with respect to N and T axes rotated 30 deg counterclockwise relative to the X and Y axes. ans: Rn = 500 lb Rt = 266 lb how did that happen?
Where can I find online help with solving statics (engineering) problems and getting an explanation of the relevant theory?
Are you looking for one-on-one tutoring or an online course?For tutoring, you can find local options (your school should have a resource with active tutors and their experience) or you can try online tutoring by using a service. Either way, I recommend asking for reviews.For an online course, there are many options out there, but most are more theoretical and don’t focus on specific problem solving strategies. Crammables offers a course specifically designed to help students understand core engineering statics theory and learn (and apply!) clear problem-solving methods.(Disclaimer: I’m the co-founder of Crammables, an online resource dedicated to engineering student success without all the sweat and stress.)
Engineering Statics(simple problem)?
Since you've got a function rather than a regular shape for your loading, you'll need to integrate. The basic idea for finding the center of an area (such as a loading) is to break the area up into pieces. Then sum(area of each piece*distance of each piece)/sum(area of all pieces) For a function, we want pieces that are a differentiably small width (dx) by the height of the function at that point. So the area of each individual piece is f(x)*dx where each piece is located at a distance x from the tip. The sum of all of these would then be integral (x*f(x)*dx) integrated from zero to the length of the wing. The area of the whole loading is integral (f(x)*dx) So your resultant of loading would be R = integral (x*f(x)*dx) / integral (f(x)*dx)
What is the easiest way to learn engineering statics?
Hi there,I graduated last year (2016) with a degree in Petroleum Engineering. I had to study engineering statics and mechanics of materia; in your first contact statics will look like very hard beleive me it is not.If you are using ribber(book) you just need to read the chapters and solve the fundamental problems because they pretty much are a summary of all the possible scenarios. Don't forget to study at least 2 hours a day(with breaks)and in the end of the first month you will see your improvement i guarantee you.
