Question
1. What are the requirements for an object to be in rotational and translational equilibrium (select all that apply)?
F= 0
m = 0
= 0
asystem = 0
system = 0
2. Suppose you are trying to turn a stubborn bolt using a wrench. You exert a force F perpendicular to the end of the wrench with a length of 8" and the bolt does not move. Frustrated, you borrow your neighbor’s 16" wrench and exert the same force F perpendicular to the end of the wrench and the bolt begins to rotate! Explain (in 2-3 sentences) why the second wrench worked using the concept of torque and its properties.
3.What is the uncertainty of the triple beam balance?
+/- 0.03 g (30 % of the least count)
+/- 0.01 g (10 % of the least count)
My measurements are perfect, I don't have uncertainties
+/- 0.02 g (20 % of the least count)
A.F= 0
B.m = 0
C.= 0
D.asystem = 0
E.system = 0
Explanation / Answer
The system is in Translational equilibrium when the sum of all the external forces acting on the object equals zero. If we can tell that an object is in translational equilibrium, we can use this to help find all the forces affecting that object. Rotational equilibrium is same of that of the first one only difference is we are dealing with torque instead of force there.
A and C are the answers.
3)d. 20% of least count
