Question: A uniform meter stick off mass Ms = 100g is supported by a pivot at its 35 cm mark. When an unknown mass is suspended from the 10 cm mark, the system is in equilibrium. What is the value of the unknown mass?
Given: Pivot point at 35 cm, and mass of meterstick = 100g.

Nevermind I think I got it.
For Pull: it would be cos(29) + (0.74)*sin(29) = 1.23
340.8 N / 1.23 = 276 N
For Push: cos(29) - (0.74)*sin(29) = 0.516
340.8 / 0.515 = 661 N
Unless otherwise stated, all objects are located near the Earth's surface, where g = 9.80 {\rm m/s^2}.
A person has a choice while trying to push a crate across a horizontal pad of concrete: push it at a downward angle of 29∘ , or pull it at an upward angle 29∘.
If the crate has a mass of...
