The large quadriceps muscle in the upper leg terminates at its lower end in a tendon attached to the upper end of the tibia (see Figure a). The forces on the lower leg when the leg is extended are modeled as in Figure b, where T is the force of tension in the tendon, w is the force of gravity acting on the lower leg, and F is the force of gravity acting on the foot. Find T when the tendon is at an angle of 25.0° with the tibia, assuming that w = 29.0 N, F = 12.3 N, and the leg is extended at an angle ? of 40.0° with the vertical. Assume that the center of gravity of the lower leg is at its center and that the tendon attaches to the lower leg at a point one-fifth of the way down the leg. (Give the magnitude.)

A uniform plank of length 2.00 m and mass 26.0 kg is supported by three ropes, as indicated by the blue vectors in the figure below. Find the tension in each rope when a 710–N person is d = 0.500 m from the left end. Answer the 3 boxes below:

It settles in the position shown on the left, where the weighted cable is vertical, the second cable is 20⁰ from horizontal, and the beam is 60° from horizontal. Find the tension in the second cable and the horizontal and vertical reaction forces at the W base of the beam.

Three main forces that act on the patella, and are shown on the diagram below. These forces are the quadriceps muscle force (FQ), the patella ligament force (FPL), and the patellofemoral joint reaction force (FPF). The angles a and ẞ are with respect to a line that is perpendicular to FPF. Assuming a = 10°, ẞ = 30°, and FQ = 4000 N, use the equations for static equilibrium to calculate the FPL in Newtons. Round to an integer, such there is no need for a decimal. FQ FPF FP B
