4. A synchronous belt transmission is used as a timing belt for an overhead camshaft on a car motor. The belt is elastically pre-stressed at standstill to make sure it does not slip at high speeds due to centrifugal forces. The belt is 1100 mm long and weighs 200 g. The elastic spring constant for 1 m of belt material is 10% N/m. The belt pre-stress elongates it 2 mm. It needs to elongate 4 mm more to start slipping. (1) Calculate the maximum allowable motor speed if the pulley on the motor shaft has a diameter of 100 mm. (ii) Find the diameter of the camshaft pulley.
