Abdomen Case Study     Talk through the case.  You are continuously recorded.    Things to remember:   Comment on measurements (normal and abnormal), any images you want to improve, any abnormalities, describe those by ultrasound terms and then give a likely diagnosis.  What would the treatment be?  What lab values would you want to see, if any?

What is the measurement cut off for an ovarian cyst versus a dominant follicle?   May type response or say orally

Which of the following situations satisfies both the first condition for equilibrium (net force = 0) and the second condition for equilibrium (net torque = 0)?

Two rods are made of the same kind of steel. The longer rod has a greater diameter. A force of magnitude F is applied to each end of each rod. Compared to the rod of length L, the rod of length 2L has:

Which of the four forces shown here produces a torque about O that is directed out of the plane of the drawing?

When recording data in the lab, which of the following should you NOT do?

A yo-yo is placed on a horizontal surface as shown. There is sufficient friction for the yo-yo to roll without slipping. If the string is pulled straight up as shown with a force of constant magnitude F:

Three force vectors are shown in the figure. All three forces act at point P. Rank the three forces in order of the magnitude of the torque that they produce about point O, a distance r = 0.500 m from point P. Rank them from largest torque to smallest torque.

The graph shows the angular velocity omega (z) and angular acceleration alpha (z) versus time t for a rotating body. At which of the following times is the rotation speeding up at the greatest rate?  

You want to double the radius of a rotating solid sphere while keeping its kinetic energy constant. (The mass does not change.) To do this, the final angular velocity of the sphere must be:
