Chapter 8, Problem 9 The coefficients of friction between the block and the rail are 0.30 s and 0.25. k Knowing that 65 , determine the smallest value of P required ( a ) to start the block moving up the rail, ( b ) to keep it from moving down.
Chapter 8, Problem 11 The coefficients of friction are 0.40 s and 0.30 k between all surfaces of contact. Determine the smallest force P required to start the 30-kg block moving if cable AB ( a ) is attached as shown, ( b ) is removed.

Unformatted text preview: A 120-lb cabinet is mounted on casters that can be locked to prevent their rotation. The coefficient of static friction between the floor and each caster is 0.30. If 32 in., h determine the magnitude of the force P required to move the cabinet to the right ( a ) if all casters are locked, ( b ) if the casters at B are locked and the casters at A are free to rotate, ( c ) if the casters at A are locked and the casters at B are free to rotate....
