The mechanism of Prob. 5/90 for pushing small boxes from an assembly line onto a conveyor belt is shown with arm OD and crank CB in their vertical positions. For the configuration shown, crank CB has a constant clockwise angular velocity of rad/s. Determine the acceleration of E.

Disk A weighs 4.00 lb and Disk B weighs 1.00 lb. Disk A is driven by a 30.0 in-lb torque as shown. Calculate the angular acceleration of Disk B.

I need the answer as soon as possible

The diagrams shows a "rocking lever" mechanism in which steady rotation of the wheelproduces an oscillating motion of the lever OA. Both the wheel and the lever are mounted infixed centres. The wheel rotates clockwise at a uniform angular velocity ( \omega  ) of 100rad/s Forthe configuration shown, determine the following.(i) The angular velocity of the link AB and the absolute velocity of point A.(ii) The centrifugal accelerations of BC,AB and OA.(iii) The magnitude and direction of the acceleration of point A.The lengths of the links are as follows.BC=25mm,AB=100mm,OA=50mm,OC=90mm
