The solid homogeneous cylinder weighs 300 lb and is free to rotate about the horizontal axis O-O. If the cylinder, initially at rest, is acted upon by the 100-lb force shown, calculate the horizontal component R of the force supported by each of the two symmetrically placed bearings when the 100-lb force is first applied.
A reaction in a batch system is assumed to be first order. Data listed below was collected. Determine the reaction rate constant.
Water in a pip has a pressure of 22.1 lb/ft2. What is the pressure head?
(a) Define the hardenability of a steel. (b) Define the hardness of a steel. (c) Describe the Jominy hardenability test. (d) Explain how the data for the plotting of the Jominy curve are obtained and how the curve is constructed.
The ball is kicked so that it has a velocity of 0.5 m/s and the cord is pulled in at a rate of 0.2 m/s. Neglect friction so that the only important force on the ball is the tension in the cord. Find the tension in the cord when the radius is 0.25 ..

Estimate the theoretical fracture strength of a brittle material ifit is known that fracture occurs by the propagation of anelliptically shaped surface crack of length
Mike and Susan hope to retire a few years early, they decided to pay closer attention to the predicted amount of retirement benefits and do some analyses on the numbers.
A 3000-lb car is traveling on a paved road with Cd (coefficient of drag) = 0.35, Af (frontal area of the vehicle) = 21ft^2, and p(air density)=0.002378 slugs/ft^3. Its engine is running at 3000rpm and is producing 250ft-lb of torque.
