Three equally sized cylinders with equal mass are stacked in a groove as shown below. Determine all forces acting on cylinder C and show them in a diagram. Begin your solution on this page Continue on additional sheet as necessary 100 100

5. The figure below represents the anatomy of the lower limb when balanced on your toes and the body weight acts through the tibia. The Achilles Tendon makes an angle (0) of 8° with the vertical and for this foot x1 is 6.2 cm and x2 is 12.3 cm. Calf Muscle Tibia Achilles Tendon Calculate the tension (T) in the Achilles Tendon if a 70 kg man stands on the toes of both feet. Using the values in this example what is the mechanical advantage for this lever and describe what that means in terms of the efficiency of the lever.

4. Not a graded question.

I just need the last problem at the bottom of the picture. When I submit the last problem by itself my question gets rejected because the value of the mass is required so I assume that you are supposed to refer to the previous problems to see that M=100Nm.
