A 80.0 kg painter stands on a uniform 4.0 m long board of mass 10.0 kg supported horizontally by two ladders as in the diagram below. Find the forces exerted by each ladder on the board. Show workings.

The two children shown in the figure below are balanced on a seesaw of negligible mass. The first child has a mass of 23.3 kg and sits 1.74 m from the pivot. The second child has a mass of 45.7 kg and sits 0.887 m from the pivot. Use the second condition for equilibrium (net t = 0) to calculate F, the supporting force (in N) exerted by the pivot. (Enter the magnitude.) F, m2 m, w W2 N

Please help and show work... these are two seperate questions but formatted the same so please  help me!!!

When the beam in situation is balanced , the Angle between the force and the lever arm 0 degrees. True & false

please, answer immediately. thank you!

A uniform beam of length 4.0 m and weight 60 N is mounted by a small hinge on a wall at it left end. The beam is held in a horizontal position by a vertical rope at its right end as shown. What is the hinge force on the beam?

A 2.93m long ladder leans against a frictionless wall. The coefficient of static friction between the ladder and the floor is 0.353. What is the minimum angle that the ladder can make with the floor without slipping? 19.4 deg Submit Answer Incorrect.
