Homework Statement
A foldable step ladder weighing 150 𝑁 is made of two halves connected by a pivot on top and
by a rope in the middle. The ladder is put on ice and its angle with the surface is 60°. What is
the tension of the rope?
Relevant Equations
net torque = zero
tried equating torques around the pivots of the ladder and equating them to zero but I'm not getting anywhere with that.

Start with some diagrams (FBD). You aren't receive help until you show an honest effort has been made.

We can't help you unless you show us what you did. Just mentioning it is not enough. We have to know where you got stuck or what you did wrong.

Welcome, @engineerr !

Could you clarify this part?
“The ladder is put on ice and its angle with the surface is 60°.”
Each half, I assume.
