Question

1. Let x = .52m and F = 34 N. What is the torque exerted by F about point P, in Nxm?

2. The uncertainties in the measurements are Ex = +- .1m and Ef = +- 37N. What is the propagated uncertainty in the torque, in Nxm?

For this question, round up your final answer to two significant figures. Do not include a +- sign in your answer.

3. Let x = 2.33m, F = 57N and theta = 38.5 degrees. What is the torque exerted by F about point P in Nxm?

4. The uncertainties in the measurements are Ef = +- 1N, Ex = +-.07m and Etheta = +- 1.9 degrees. What is the propagated uncertainty in the torque, in Nxm?

Tip: For this question, you have to find the uncertainty propagation through a product of three factors. It might be easier to first propagate through the first two, then include the third.

For this question, round up your final answer to two significant figures. Do not include a +- sign in your answer.

5. Let m1= 4.4 kg and m2 = 1.2 kg. Use the first equilibrium condition to find the tension in the cable, in N.

6. With the same masses as in the previous question, let x1 = 1.1m and x0 = 0.4m. Use the second equilibrium condition to find x2, in m. Take all the torques relative to point P.

Explanation / Answer

Multiple question. I am not allowed to answer multiple question at a time. Question 1 and 3 are relatedO So i am answering both

1.
T = F*L*sin thetha
= 34*0.52* sin 90
=17.68 Nm

3.
T = F*L*sin thetha
= 57*2.33* sin 38.5
=82.68 Nm
