The 3 side will be higher, no? But how do we find the missing side of the right angle triangle? c^2 = a^2 + b^2 would give the missing height, but a different answer depending on if the 3m side is used or the 4m side is used.
To solve this, all i would need is the angles of the right angle...
Homework Statement
A 5m long uniform beam AC with mass of 600kg is being lifted from the ring at B by two chains (AB, 3m long and CB, 4m long). Determine the tension in chain AB and CB when the beam is clear of the ground.

I think I've got it.
With this formula
T sin(theta) = W/2
i can get the angle cause i know the max tension, but then how do i get the length of the chain from that?

Hi guys, really stuck on this one.
A 1000N black is to be lifted using a chain sling (as shown). If the tension in the chain sling is not to exceed 1300N, find the shortest sling ABC that can be used.
A is the most left point, B is the most right point and C is the top...
