PHYSICS: Great work today thinking through these problems! A couple of things that work for me – draw them first. Then go back through and separate resultants into components. If an object is in equilibrium, then there are no net forces – all the forces in the x direction balance – everything left equals everything right, and all the forces up equal all the forces down.
You’ve got all the ammo you need, now go forth and conquer!
UPDATE: Answers below:
- Fn = 3430 N upward against feet
- Fn,1 = Fn,2 = 1890 N upward on each foot
- Fforward = 4.59 N
- FT,1 = FT,2 = 1760 N
- FT,1 = 1.36 × 103 N and FT,2 = 680. N
