2) A shaft of a diameter of 30 mm is transmitting 14,9 kW at 400 rpm. The shaft is connected to a pulley of an axial length of 160 mm with the help of a rectangular key 16 mm x 12 mm ( b=16 mm, t=12mm). (The spokes are connected to the pulley, but the pulley is not shown in the figure). Axial length of the key, hub and pulley are 160 mm. Determine the shear and normal stresses developed in the rectangular key. Rectangular key Spokes A R Hub Shaft

HW3) PQRS is a four bar chain with link PS fixed. The lengths of the links are PQ = %3D 62.5 mm ; QR = 175 mm ; RS = 112.5 mm ; and PS = 200 mm to be vertical. %3D The crank PQ rotates at 10 rad/s clockwise. Draw the velocity and acceleration diagram when angle QPS = 120° and Q and R lie on the same side of PS. Find the angular velocity and angular acceleration of links QR and RS.
pl very urgent and quick
this is an mechanical engineering queation.
