The square plate is attached to a short link at A and a roll

The square plate is attached to a short link at A and a roller at C. At the instant shown, the control link OA has a counterclockwise angular velocity of 4 rad/s. if the speed of point C is slowing down at the rate of 50 mm/s2, determine at the instant shown: a. The angular velocity of the square plate omega_AC. b. The angular acceleration alpha_OA of the link OA. c. The angular acceleration of the square plate alpha_AC Solve the problem using any method. omega_AC = alpha_OA = alpha_AC =

Solution

select the lightest W-shape (using A992 Grade 50 material) that will provide

a factor of safety against tensile yielding equal to 1.67,

a factor of safety against shear yielding equal to 1.50, and

a maximum transverse deflection that does not exceed L/480.
