RP7-17) A light flywheel rotates freely on a shaft located at its center (point o). The flywheel is attached to two masses as shown in the figure. Mass A (mA = 50 kg) is attached to the inner radius (r; = 10 cm) of the flywheel though an inextensible rope. Mass B (m3 = 20 kg) slides along a rough horizontal surface (uk = 0.3) and is attached to the flywheel's outer radius (r = 20 cm) through an inextensible...
Rod OA rotates counterclockwise with a constant angular velocity of θ = 5 rad/s
Rod OA rotates counterclockwise with a constant angular velocity of θ = 5 rad/s. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r = 1.5(2-cosθ)ft. (Figure 1) Part AIf both collars weigh 0.80 lb, determine the magnitude of the normal force which the curved rod exerts on one collar at the instant θ = 135°....
