Atwood’s machine consisted of two masses connected by a string that passes over a pulley, as shown below. The hanging mass m2 accelerates in the downwards direction. I also apply a small opposing upwards force F = 1⁄4 m2g on the bottom on the mass m2 but the mass m2 continues to accelerate in the downwards direction. (a) Find the Tension of the masses in terms of m1 and m2. (b) Calculate the numerical value of the Tension if m1 = 3.1 kg and m2 = 5.4 kg.

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
