369737 If the ratio of lengths, radii and Young's modulii of steel and brass wires in the figure are \({a, b, c}\), respectively, then the corresponding ratio of increase in their lengths would be

369738 Match the Column I and Column II


Choose the correct answer from the options given below

369739 Assertion :
Spring balance shows incorrect readings after using it for a long time.
Reason :
Spring in the spring balance loses its elastic strength over the period of time.

369740 The bar shown in the figure is made of a single piece of material. It is fixed at one end and consists of two segments of equal length \({\dfrac{L}{2}}\) but different cross-sectional area \({A}\) and \({2 A}\). What is the change in length of the entire system under the action of an axial force \({F}\) ?
