The discussion focuses on calculating the tipping point of a wooden plank with a total mass of 7 kg and a length of 4 m, supported by two sawhorses located 0.45 m from the left end and 1.5 m from the right end. When a cat weighing 3.9 kg jumps on the left end and walks towards the right, the critical distance from the right end at which the plank tips is determined by balancing the moments around the sawhorse on the right. The solution involves applying principles of static equilibrium and torque calculations to find the exact tipping distance.

I don't see your attempt.Mcdeltateta said:1. Given a wooden plank mass 7 kg total length 4m supported by 2 sawhorses which are located l1=0.45m from left end and l2=1.5m from right end ...a cat with mass 3.9kg jumps on left end of plank and walks along to right side . How far is it from the right when plank begins to tip ?
