The motion of an oscillating crank is defined by the relation e=6sin(rt/4)-3sin (nt/2) where 'e' is expressed in radians and 't' in seconds. Determine the angular displacement, the angular velocity, and the angular acceleration of the crank when (a) t=0s, (b) t=2s. (c) Draw the graph of the angular displacement, angular velocity and angular acceleration from t=0 to t=2. (d) solve what time will the crank starts to decelerate? Hint: at this time the angular acceleration becomes zero before becoming (-). (0.20) rad/s

1. The motion of an oscillating crank is defined by the relation e=6sin(rtt/4)-3sin (nt/2) where 'e' is expressed in radians and 't' in seconds. Determine the angular displacement, the angular velocity, and the angular acceleration of the crank when (a) t=0s, (b) t=2s. (c) Draw the graph of the angular displacement, angular velocity and angular acceleration from t=0 to t=2. (d) solve what time will the crank starts to decelerate? Hint: at this time the angular acceleration becomes zero before becoming (-). a = (0.20) rad/s²
