50 N at each end
50 N at the centre
100 N at the centre
none of these.

Reaction from water is coming as UDL of magnitude 100/length resultant of which will be again its centre.

I think B is the right answer.

50 N at the centre is the right answer.

50 at each end.

Because shear force acts at the ends of the beam a.

According to me, 50 N at center is the right answer.
Because there are applied to Beyonce's force.

50N at centre is the correct answer.

Water exerts a resisting force equal to the applied point load of 100 N in the form of UDL over the whole span.

Let's say, the span is 10m long then, W=10N/M.

Now, the beam is loaded with UDL of 10N/M in an upward direction and a point load at the center.

From the SF diagram maximum shear 50N at the center.

@Civise.

Because the log is floating. So forces are balancing each other. That's why.

How do guys consider the udl of water is 50? Please explain it detail.
