An elevator car has two equal masses attached to the ceiling as shown. (Assume m = 4.10 kg.) (a) The elevator ascends with an acceleration of magnitude 1.70 m/s², what are the tensions in the two strings? (Enter your answers in N.) T, = 108 24 Draw free-body diagrams for each mass. What forces act on each mass? What are the directions of the forces due to each rope on the upper mass? How are the forces that the lower rope exerts on the mass. You might find it easier to solve for T, first, then use your result when solving for T,. N T2 - 54.12 Draw free-body diagrams for each mass. What forces act on each mass? What are the directions of the forces due to each rope on the upper mass? How are the forces that the lower rope exerts on the mass. You might find it easier to solve for T, first, then use your result when solving for T. N (b) The maximum tension the strings can withstand is 101.2 N. What is the maximum acceleration of the elevator so that a string does not break? (Enter the magnitude in m/s².) 1.27 Note that the tension is greater in the upper string, so this string will break first. Find a when T; = Tmax" m/s?

Include a free body diagram please.
A warehouse worker pushes a crate along the floor, as shown in the figure (Figure 1), by a force of 19 NN that points downward at an angle of 45 degrees below the horizontal. Find the horizontal component of the push. Your answer should be positive if the force is to the right, negative if the force is to the left. Express your answer in newtons. Find the vertical component of the push. Your answer should be positive if the force is upward, negative if the force is downward. Express your answer in newtons.

A cabinet of mass 3.7 kg is at rest on a ramp as shown. What is the magnitude of the friction force on the cabinet, in Newtons? The coefficients of friction between the cabinet and ramp are Ps = 0.850 and uk = 0.750. Use g = 10 m/s2. (Hint: what type of friction is it?) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 30.0
Find the unknown mass of the block 1 needed to balance the bar. Assume that the mass of the bar is negligible. Block 1 is located 0.85 m left of the center of the bar. Blocks 2 and 3 are located at 0.25 m and 0.50 m right of the center of the bar. The masses of the blocks 2 and 3 are showed. Give the result in the nearest whole number. Do not include units in the result. Hint: the only acting force is the weight. This problem is about torque.
