engineering recuitment GATE CE 2023-24 Test Series Strength of Materials Simple Stress and Strain Stress and Strain
A rigid beam of negligible weight is supported in a horizontal position by two rods of steel and aluminum 2 m and 1 m long having cross-sectional areas 1 cm2 and 2 cm2 and Modulus of elasticity E of 200 GPa and 100 GPa respectively. A load P is applied as shown in the figure. If the rigid beam is to remain horizontal:
1
The load on both the rods should be equal
2
The load on aluminum rod should be twice the load on steel
3
The load on steel rod should be twice the load carried by aluminum
4
The load P must be applied at the center of the beam
