Two equal masses are connected on either side of a pulley. One of the masses rests on an inclined plane with angle of inclination of b. The other one hangs in mid air.
The moment of inertia of the pulley about its axis of rotation (the center of mass lies on the axis of rotation) is Ig.
Assuming that the string is inextensible, that it rolls without slipping on the pulley, and there's no friction in the pulley bearing/between the inclined plane.
1. Find the the acceleration of each mass.2. Find the tension in the string on each side.3. Find the angular acceleration of the pulley.
A vessel with a volume of 0.0011 m3 is filled with dry saturated steam at a pressure of 95 kPa. It is then sealed and cooled to 250C. Determine the amount of heat that must be removed.
Two tow trucks lift a 660 lb motorcycle out of a ravine following an accident. If the motorcycle is in equilibrium in the position shown, what are the tensions in cables AB and AC?
If the filling is done rapidly, calculate the final temperature in the small cylinder, (a) assume that oxygen is an ideal gas with Cv= 5R/2 and (b) using accurate thermodynamic data for oxygen.
Calculate the overall heat transfer coefficient between the air and the water (answer in W/m^2K).
The acceleration of the car is defined by a=(2t^2+t)m/s^2. Find the position of the car at t = 3 seconds. The car starts from rest.
While jogging on the beach (it's a warm summer day, about 30 deg C) a high-speed jet flies overhead. You guesstimate it's an altitude of about 3500 m, and count off about 5 s before you hear it. Estimate the speed and Mach number of the jet.
A 9º wedge is inserted using a force of 1000 lbs. The static coefficient of friction between the wedge and the log is 0.50. Determine the force required to pull the wedge out.
