Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

Question

I was not sure how to write the equllibrium equations for this problem and find P.

3.4-7 Force P is applied to Block 2 parallel to an
inclined smooth surface to hold the two blocks in
equilibrium (see figure). The blocks are connected

Two boxes are connected to a cord, and the cord is hung over a pulley connected to the ceiling, as shown in the figure below. MO R The masses of the boxes are m = 17.0 kg and m, 1 = 11.0 kg, the mass of the pulley is M = 5.00 kg, and the radius of the pulley is R = 0.300 m. Box m, is initially on the floor, and box m, is initially 4.70 m above the floor when it is released from rest. The pulley's axis has negligible friction. The mass of the cord is small enough to be ignored, and the cord does not slip on the pulley, nor does it stretch. (a) How much time (in s) does it take box m, to hit the floor after being released? At, = Apply Newton's second law to each box. Consider the forces on each box and be careful of directions and signs of forces and acceleration.
