Knowing that the coefficient of static friction is 0.40 between both collars and the rod, determine whether the plate is in equilibrium in the position shown when the magnitude of the vertical force applied at E is (a) P-0, (b) P=20 lb. 2n E G 50 Ib c
The 50-lb block A and the 25-lb block B are supported by an incline that is held in the position shown. Knowing that the coefficient of static friction is 0.15 between all surfaces of contact, determine the value of ? for which motion is impending. Fig. P8.12
The 3-lb uniform rod BD is connected to crank AB and to a collar of negligible weight. A couple (not shown) is applied to crank AB causing it to rotate with an angular velocity of 20 rad/s counterclockwise and an angular acceleration of 88 rad/s2 clockwise at the instant shown. Neglecting the effect of friction, determine the reaction at D. Problem 16.125 - General plane motion: Uniform rod: Equations of motion The 3-lb uniform rod BD is connected to crank...
Prob. A 20-b uniform disk is placed in contact with an inclined surface and a constant 7.5 lb-ft couple M is applied as shown. The weight of the link AB is negligible. Knowing that the coefficient of kinetic friction at D is 0.4, determine (a) the angular acceleration of the disk, (b) the force in the link AB. a rough horizontal surface and end B supported by a smooth vertical surface.

A 24 lb uniform slender rod AB of length L= 36 in is fixed to a 12 lb uniform disk of radius, R= 12 in , and both are pinned at B as shown. A belt is attached to the rim of the disk and then to a spring with spring constant, k= 40 lb/in which holds the rod/disk at rest in the equilibrium position shown. natural period is 0.446 s If end A is displaced a distance of 0.9...
