A student's head is bent over her physics book. The head weighs P = 25.6 N and is supported by the muscle force Fm exerted by the neck extensor muscles and by the contact force Fc exerted at the atlantooccipital joint. Given that the magnitude of Fm is 60.0 N and is directed 35.0° below the horizontal. PN Find the magnitude of the contact force F. . |N
A patient with a broken leg stands using a pair of crutches. The crutches support 75% of the 78 kg patient’s weight. Find the force each crutch applies to the patient, assuming they are held pointed slightly outward from the person’s sides, each making a 15 degree angle with the vertical. Please include any diagrams if possible.

A block of weight w is suspended from a rope tied to two other ropes at point O. One rope ishorizontally attached to a wall and the other is fastened to the ceiling. The angle betweenceiling and the rope is 60°. What are the tensions in each of the ropes? Assume the weights ofthe ropes and the knots are negligible. If the weight of the block is 100 N, what is the tension inthe ceiling rope?

A mass of 8.5 kg is supported by equilibrium by two ropes. The rope pulls in a direction of 35 degrees with the horizontal and the other rope in a direction of 43 degrees with the vertical.Show FBD
Two vertical ropes support a 2.00 meter 500N sign. The sign is uniform so its weight force acts at its center. The left rope exerts an upward tension force , T1, and it acts at the far left edge of the sign. The right tension force, T2, acts 0.57 meters to the left of the far right edge. Solve for the values of the two tension forces
