Q.13.
Which of the following is NOT a type of shaft-to-adjacent-shaft power transmission?
Q.14.
It is a way of transmitting mechanical power from one place to another which is common in motorcycles and bicycles.
Q.15.
Power is transferred between an electric motor and a pump with a chain drive. Calculate the required number of driven sprocket teeth and chain length if the motor and pump areinches apart, and the driven shaft must rotate atr/min. The driving sprocket is installed directly on the motor shaft and hasteeth. The plate on the motor indicates a nominal speed ofr/min. The chain has a pitch of 0.5 inches.
