Need help with problem #4 and #6
don't know where to start
The Attempt at a Solution
attempt at number 4, I used T1 T2 T3 as tension for each side, since the weight is the force downward the two side that connect to the weight so each side should get half, 274 N and using tangent. I got 548/tan(60) and got 316.387N is this right?
number 6 I understand the CG of the block must get past the rotational point at the bottom right corner
