Design rate of super elevation for horizontal highway curve of radius 450 m for a mixed traffic condition, having a speed of 125 km/hour is

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 (τ_{vf , cal}) and axial tensile stress (σ_{tf , cal}) shall be so proportioned that the stresses do not exceed the respective allowable stresses τ_vf and σ_tf and the value of exceed does not exceed

Standard 5-day BOD of a waste water sample is nearly x% of the ultimate BOD, where x is

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
