Calculate the deflection if the slope is 0.0225 radians. Take the distance of centre of gravity of bending moment to free end as 2 metres.

Civil Engineering : Strength of Materials - Quiz(MCQ)

49mm

45mm

35mm

28mm

Correct Answer : 45mm

Explanation : The deflection at any point on the elastic curve equal to Ax/EI

But, we know that A/EI is already slope equation.

So, slope × (the distance of centre of gravity of bending moment to free end = 2m).

0.0225 × 2

0.045m ~ 45 mm.

The structures constructed along are distributaries are called as _______

Inlets

Outlets

Channels

Distributaries

Correct Answer : Option (B) : Outlets

Explanation : An outlet is a simple and small irrigation structure which is constructed along the distributaries. The amount of water that is withdrawn through the outlet is in proportion to the area that is irrigated below respective point.

Major distributaries discharge varies from _______

0.25 to 5 cumecs

2 to 4 cumecs

1.5 to 5 cumecs

1.2 to 5 cumecs

Correct Answer : Option (A) : 0.25 to 5 cumecs

Explanation : The major distributary takes off from a branch canal to distribute the water to various parts of the field. The supply of the water varies from 0.25 to 5 cumecs.
