p1(4).png A simple pendulum consists of a point mass  oscillating on the end of a massless string of fixed length L under the influence of gravity.  Determine the angular acceleration of the simple pendulum shown for L = 1.50 m when the angle q = 35.00.

p1start(1).png A mass m = 60.0 g is fixed to the end of a rigid rod of length L = 40.0 cm pivoted about the other end.  A torque of 0.120 Nm is applied to accelerate the system.  Determine the acceleration of the system if the rod has a mass of 75.0 g.

Which is the most likely cause for this scenario: One screening cell of the AbSc was observed as 1+ at antihuman globulin phase, while the patient ABO type was identified as A Pos.

During donor testing, the sample was found positive for the antibody screen. How should the collection center proceed with the donated unit?

p8(2).png A uniform meter stick of mass 125 g has masses m1 = 50.0 g at the 0.0 cm and m3 = 250 g at the 100 cm position and balances when pivoted about the 70.0 cm position with the mass m2 at the 30.0 cm position.  What is the mass m2?

Determine the moment of inertia for a 1.8 m long uniform rod of mass 250 g pivoted about the center.
