The beams, one having square cross section and another circular cross-section,are subjected to the same amount of bending moment. If the cross sectional area as well as the material of both the beams are the same then

Maximum shear stress developed on the surface of a solid circular shaft under pure torsion is 240 MPa. If the shaft diameter is doubled then the maximum shear stress developed corresponding to the same torque will be

A simply supported laterally loaded beam was found to deflect more than a specified value. Which of the following measures will reduce the deflection?

The mechanism used in a shaping machine is
