A wire of uniform cross - section is suspended vertically from a fixed point , with a load attached at the lower end . Calculate the fractional change in frequency of the wire due to rise in temperature by `t^(@) C`. The coefficient of expansion of the wire is `alpha`.

A wire ofuniform cross-section is suspended vertically from a fixed point , with a load attached at the lower end. Show that the change in frequency related to the altered frequency of the wire due to rise in temperature is approx (1)/(2) alpha t, Where alpha is the linear coefficient of expansion of the wire and t^(@)C is small rise in temperature.

A metal wire of length L is suspended vertically from a rigid support. When a bob of mass M is attached to the lower end of wire, the elongation of the wire is l:

Define stress. A heavy wire is suspended from a roof and no weight is attached to its lower end. Is it under stress.

A heavy wire is suspended from a roof but no weight is attached to it lower end. Is it under stress. Explain?

A steel wire of unifrom cross-section 1 mm^(2) is heated to 70^(@)C and strechted by tying it two ends rigidly. Calculate the change in tension on the wire when temperature falls form 70^(@)C to 35^(@)C

A wire suspended vertically from one of itsends is strached by attached a weight of 200 N to the lower end . The weight streches the wire by 1 mm . Then the elastic energy stored in the wire is
