Physics 10-24-16 And Did the Hammock Crash?

PHYSICS: Great work today thinking through this one and also the “Wanda has a sign” problems! How you look at problems from the beginning can make a huge difference – huh?

A couple of things that work for me when doing equilibrium, etc., problems – first, draw them. 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!

Answers for the Equilibrants II worksheet are below:

  1. Fn = 3430 N upward against feet
  2. Fn1 = Fn2 = 1890 N upward on each foot
  3. F forward = 4.59 N
  4. T1 = T2 = 1760 N
  5. T1 = 1360 N and T2 = 680. N

  1. I would give myself 3 out of 5 stars for this week. I did well the labs and activities we did in class, and these helped reinforced my knowledge in the subjects. I did well some of the homework, but i had trouble with Zorba. Explaining it in class helped me, but I need to continue to practice on problems like this one. I also I had trouble explaining Newton’s Third Law in the lab, but today’s lecture helped explain it well.
