A shaft is supported on bearings A and B, 800 mm between centres. A 20° straight tooth spur gear having 600 mm pitch diameter, is located 200 mm to the right of the left hand bearing A, and a 700 mm diameter pulley is cross mounted 250 mm towards the left of bearing B. The gear is driven by a pinion with a downward tangential force while the pulley drives a horizontal belt having 180° angle of wrap. The pulley also serves as a flywheel and weighs 2000 N. The maximum belt tension is 3000 N and the tension ratio is 3 : 1. Calculate the maximum bending moment and the required shaft diameter if the allowable shear stress of the material is 40 MPa.
Q. What is polymers? The term "polymer" is derived from the two Greek words: poly, meaning "many", and meros meaning "parts" or "units". Thus polymers are composed of a large n
