1.692m, but you should have included a diagram, I am still not sure if you are talking about a cantilever force couple or a simple lever pivot..
A 70 kg painter is painting the wall of a building. He stands on a horizontal .. Physics help!!!?
A 70 kg painter is painting the wall of a building. He stands on a horizontal board of length 5.4 m and mass 15 kg, suspended from vertical ropes attached to each end. If the painter stands 1.8 m from one end of the board, what would the tensions in the ropes be? a) tension in rope nearer to the painter ?? N b) tension in rope further from the painter ?? N
While standing on a long board resting on a scaffold, a 80-kg painter paints the side of a house, as shown in the figure (Figure 1) .?
A. If the mass of the board is 16kg , how close to the end can the painter stand without tipping the board over? Express your answer using two significant figures. In m from left end of the board.
While standing on a long board resting on a scaffold, a 60 kg painter paints the side of a house?
While standing on a long board resting on a scaffold, a 60 kg painter paints the side of a house. If the mass of the board is 13 kg, how close to the end can the painter stand without tipping the board over?
If the mass of the board is 18 kg , how close to the end can the painter stand without tipping the board over?
assuming board is uniform, cg at midway; also assuming support from two ends at 1.5m taking moment about one support, when the board is about to tip, reaction on the other support is 0; 18 * g * ( 2.5 / 2 ) = 75 * g * (1.5 - d) where d is distance from one end. 18 * ( 2.5 / 2 ) = 75 * (1.5 - d) 0.3= 1.5 -d d = 1.2 m from the end answer
A scaffold of mass 51 kg and length 5.7 m is supported?
in a horizontal position by a vertical cable at each end. A window washer of mass 68 kg stands at a point 0.58 m from the end. What is the tension in (a) the nearer (relative to the person) cable and (b) the farther (relative to the person) cable?
