Chapter 8, Problem 50P

The man pushes the 60-kg homogeneous crate with the horizontal force P. Determine the largest distance h for which the crate will slide without tipping.

Find the minimum force P required for impending motion of the block up the inclined surface, given: Mblock = 65 kg, θ = 52 °, μ = 0.4

= The smooth pin P has a mass of 80 g. It is attached to an elastic cord extending from 0 to P and, due to the slotted arm guide, moves along the horizontal circular path r = (0.8 sin ) m. If the cord has a stiffness k 30 kN/m and an unstretched length of 0.25 m, determine the force of the guide and the normal force of the circular path on the pin when 0 = 60°. The guide has a constant angular velocity è = 5 rad/s. T P ė = 5 rad/s 0.
