Question

=0.01328 mm (Ans.)
Example 160. A rigid bar 3,5 metres in length is hinged at L and is supported by steel rod SM
and copper rod PN as shown in Fig. 1,66 (a). If the lengths of SM and PN are 1 m and 0.75 m and
cross-sectional areas 2 cm and 4 cm respectively, determine:
(1) Stress in each of the rods:
(ii) Elongation of the steel rod if a load of 100 kN is applied on the bar at a distance of 2.5
metres from the hinge.
Take;
E
= 1.2 x 10kN/m?
and
E
= 2 x TokN/m2
The bar is horizontal prior to the application of the load.​

Answer 1

Answer:

Explanation:

Elongation of the steel rod if a load of 100 kN is applied on the bar at a distance of 2.5

metres from the hinge.

Take;

E

= 1.2 x 10kN/m?

and

E

= 2 x TokN/m2

The bar is horizontal prior to the application of the load.​
