A spring is stretched by applying a load to its free end. The strain produced in the spring is
Upto which point on stress - strain graph of a metal wire, the material remains elastic?
The maximum load which a wire can with stand without breaking, when its length is reduced to half of its original length, will
What would be the ratio of breaking maximum load of circular rod (radius r) to maximum load, if same rod is moulded into square rod of same length?
A rectangular frame is to be suspended symmetrically by two strings of equal length on two supports (as shown in figure below) in three different ways
The tension in the strings will be
A wire of length l is tied to the ceiling and weight w is tied to the lower end. If now put on pulley and weight w is attached to both sides of wire. Then, total extension in wire would be
Two wires of the same length and same material but radii in the ratio of 1:2 are stretched by unequal forces to produce equal elongation. The ratio of two forces is
How many elastic coefficients are required to describe the elastic properties of solids?
The temperature of a wire is doubled. The Young's modulus of elasticity
Which of the following statement(s) is incorrect?
