DRAW A FREE BODY DIAGRAM! The Achilles’ tendon inserts on the calcaneus (the heel bone) at a distance of 8 cm from the axis of the ankle joint. If the force generated by the muscles attached to the Achilles’ tendon is 3000 N and the moment arm of this force about the ankle joint axis is 5 cm, what torque is created by these muscles about the ankle joint? (Show all work, and draw a free body diagram)

You push on a rectangular door at the location of the knob (see diagram for top view). The door s mass is 72.8 kg, and its side-to-side width is 1.65 m. The knob is located 0.15 m from the right-hand side of the door. If you push with a force of 133 N, what will the be the door s angular acceleration as it swings on its hinges? (Note: the moment of inertia of the door of mass M and width x, swinging on its hinges, is (1/3) M x^2.)

A force of magnitude 30 lbs acts on the end of a wrench as shown.  The wrench is 8 inches long and makes an angle of 30° from the  -x axis in the x-y plane as shown.  What is the torque exerted by this force around point P?  Give the magnitude and direction as a vector.

You push on a rectangular door at the location of the knob (see diagram for top view). The door s mass is 74.0 kg, and its side-to-side width is 1.51 m. The knob is located 0.17 m from the right-hand side of the door. If you push with a force of 140 N, what will the be the door s angular acceleration as it swings on its hinges?

A 5.0-kg ball and a 2.0-kg ball are placed at opposite ends of a massless beam so that the system is in equilibrium as shown. What is the value of lengths, x? If the 2 kg mass is taken out, what will be the torque exerted on the 5 kg ball?

The class I'm taking is physics for scientists and engineers! Need help. I have attached the problem.  Thank you so much!

The figure below shows an outstretched arm (0.61 m in length) that is parallel to the floor. The arm is pulling downward against the ring attached to the pulley system, in order to hold the 98 N weight stationary. To pull the arm downward, the latissimus dorsi muscle applies the force M in the figure, at a point that is 0.069 m from the should joint and oriented at an angle of 29°. The arm has a weight of 47 N and a center of gravity (cg) that is located 0.28 m from the shoulder joint. 0.61 m 0.28 m 0.069 m Axis at 98 N shoulder joint cg 29 Aldentify all the forces on the arm and draw an accurate and complete free body diagram on both the arm and the 98 N weight. You may draw on the figure if you wish. B Write down the correct equation of motion ON THE 98 N WEIGHT by summing all the forces acting on it using Newton's 2nd Law of Motion. You must identify and draw your chosen coordinate system. ( Write down the correct equation of motion ON THE ARM by summing all the forces acting on it…
