The cylinder of a hydraulic ram is of 6 cm internal diameter. find the thickness required to withstand an internal pressure of 40 N/mm², if the maximum tensile stress is limited to 60 N/mm² and the maximum shear stress to 50 N/mm².

The beam PQR shown in given figure is horizontal. The distance to the point of contraflexure from, the fixed end P is _____m. (up to two decimal place)

A hollow steel shaft 1.5 m long is to transmit a torque of 80 kN-m. What will be the inside diameter (in mm) of shaft, if the angle of twist should not exceed 1 ° and the allowable shear stress is 90 MPa?
[Take G = 85 GPa]

A piece of material is subjected to two perpendicular stresses 112 N/mm² (tensile) and p (compressive). If the strain energy due to both the stresses is same as a stress of 128 N/mm² acting alone, then the compressive stress, p (in N/mm²), is
[Take Poisson’s ratio (μ)= 0.3]

A steel column of diameter 150 mm is subjected to a compressive loading. In order to prevent the tension anywhere in the cross section of the column, the load should be restricted inside the kern of the column. The diameter of the kern is ______mm
