A steel rod 35 mm in diameter is inserted inside a copper tube of 40 mm internal diameter and 45 mm external diameter, the ends are rigidly connected together. If temperature of composite assembly is raised by 65 0C, What will be the stresses in steel and copper? Take ES = 200 Gpa, EC = 100 Gpa, αS = 12 x 10-6 per 0C, αC = 18 x 10-6 per 0C

A uniform ladder, of length 5 m, is supported by a horizontal floor at ‘A’ and a vertical wall at ‘B’ and makes an angle of 60° with the horizontal. Find the maximum distance ‘x’ up the ladder at which a man of weight 700 N can stand without causing slipping of the ladder. The coefficient of friction between floor & ladder and wall & ladder is 0.3. Neglect the weight of ladder.
A force system is shown in fig. determine resultant of this system and replace this resultant by equivalent force-couple system at origin.
A weight W is suspended from the ceiling with the help of rope as shown in fig. Find value of weight W.
A tension test was performed on a steel specimen of 16 mm diameter in which an axial load of 2 kN produced an elongation of 0.05 mm in a length of 80 mm, while diameter suffered a compression of 0.0035 mm. Calculate the values of change in volume, Poisson’s ratio, modulus of elasticity and modulus of rigidity.
External and internal diameter of a propeller shaft are 400 mm and 200 mm respectively. Find maximum shear stress developed in the cross-section when a twisting moment of 50 kN.m is applied. Take modulus of rigidity C = 0.8 x 105 N/mm2. If span of shaft is 4 m, also find twisting angle of shaft.
