Answer 3

So the written part would be
r plus l minus 500 minus 150 minus 150 equal 0
r plus l equals 800 and then the triangle is an isosceles triangle which would mean it has a right angle so
r equal l equals 400 n
A crucial part is that people forget this side you HAVE to use the summation of the torque
I want you to do the rest of the problem worked out until your answer is t=899 n
