Static Equilibrium Points 30 A Plank Of Length L 4 0 M And Mass M 7 4 Kg Rests On The Ground And On A Frictionless 1 (232 KiB) Viewed 32 times

Static Equilibrium Points:30 A plank, of length L = 4.0 m and mass M = 7.4 kg, rests on the ground and on a frictionless roller at the top of a wall of height h = 2.00 m (see Figure). The center of gravity of the plank is at its center. The plank remains in equilibrium for any value of > 62° but slips if < 62°. Calculate the magnitude of the force exerted by the roller on the plank when = 62°.
