Unformatted text preview: the distance from point C to where it hits the horizontal surface at D . Also, what is its velocity when it strikes the surface? 3) (25 points) Rod OA rotates counterclockwise with a constant angular velocity of ࣂ ሶ =5 rad/s. The double collar B is pinconnected 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(2cos ) ft, where θ is in radians. If both collars weigh 0.75 lb, determine the normal force which the curved rod exerts on one collar at the instant =120 degrees. Neglect friction. 4) (25 Points) The 5kg package is released from rest at A . It slides down the smooth plane which is inclined at 30 degrees, and then onto the rough surface having a coefficient of kinetic friction k = 0.2. Determine the total time of travel before the package stops sliding. Neglect the size of the package....
