A solid sphere of moment of inertia (2/5) MR^2 rolls without slipping down an incline plane of 30 degrees from a height of 8 meters. It has a mass of 82 kg and a radius of 3m. What is the velocity at the bottom?
For the venture section, calculate the velocity,mass flow rate, volume flow rate and the pressure at station two (the throat)with the properties of station one are as follows: Pressure is equal to 1.05 Bar, the temperature is recorded at 72 degrees F..
The pulley system is used to lift a 61 kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. The crate is rising with an acceleration of 2.4 m/s2. Assume the masses of the ch..
