Thanks in advance.-Taking B as fulcrum,RA * 2 + 78 * 1 = 687 * 0.RA = 132.2RB = 78 * 1 + 687 * 2.RB = 897.......

Answers are there so its working out and approach to the question I am after.

Thanks in advance.

Taking B as fulcrum,

RA * 2 + 78 * 1 = 687 * 0.5
RA = 132.75N

Taking A as fulcrum

2RB = 78 * 1 + 687 * 2.5
RB = 897.75N
