A plan represents a rectangular area of 61965 m² and measures 8.5 cm by 10 cm. What is the scale of the map?

Two bars of different materials and same size are subjected to the same tensile force. If the bars have elongation in the ratio of 3:7, then the ratio of modulus of elasticity of the two materials will be

Consider if the following statement is correct as per assumptions of Euler’s theory

A concrete beam is post tensioned by a cable carrying a prestress of 900 N/mm². At the jacking end, the slip was observed to be 8 mm. Find the percentage loss of stress due to anchorage slip if length of the beam is 20 m. Take E_s = 210 KN/mm²

The difference between maximum void and minimum void ratio of a sand sample is 0.30. If the relative density of this sample is 66.6% at a void ratio of 0.40, then the void ratio of this sample at its loosest state will be:

Bulking of sand is maximum if the percentage of moisture content is of the order of
