A mild steel specimen is under uni-axial tensile stress. Young's modulus and yield stress for mild steel are 2 x 105 MPa and 250 MPa respectively. The maximum amount of strain energy per unit volume that can be stored in this speciment without permanent set, is
-
Rivets and bolts subjected to both shear stress (τvf , cal) and axial tensile stress (σtf , cal) shall be so proportioned that the stresses do not exceed the respective allowable stresses τvf and σtf and the value of exceed does not exceed

A two lane single carriage-way is to be designed for a design life period of 15 years. Total two-way traffic intensity in the year of completion of construction is expected to be 2000 commercial vehicles per day. Vehicle damage factor = 3.0, Lane distribution factor = 0.75. Assuming an annual rate of traffic growth as 7.5%, the design traffic expressed as cumulative number of standard axles, is
