A rectangular log of wood is floating in water with a load of 100 N at its centre. The maximum shear force in the wooden log is
50 N at each end
50 N at the centre
100 N at the centre
none of these.

Maximum shear force is v suffix u = w.

= 100 N at the centre.

Because the load is passed through the shear center. It's floating 100 is right and acts at center.

100 is the correct answer. I agree.

Answer is B.

@All.

Here, you haven't considered the UDLof water which is 100/ total length. And the question of shear centre does not arise.

Pushkar said:   8 years ago
Explain your answer clearly @Himanshu.

PRATUL SHARMA said:   8 years ago
The UDL of water will act in the opposite direction of the 100 kN. And thus the answer is 100-50 = 50.

Deb said:   8 years ago
I agree @Himanshu and @Pratul.

According to given options answer should be 50 N.

But under a point load shear force is always indeterminate.

Gmg said:   7 years ago
The answer is A, each end 50, not centre, sf of udl at centre is zero.

The answer is option B.
