A crate with dimension 12 x 10 x 4in and a mass of 120 lbs slides on an inclined plane of dimension 80 x 10 x 3in. Answer the following questions:
1. Model the system in ADAMS without friction and compare your result with the analytical solution.
2. Model the system in ADAMS with friction coefficients, μs=0.4 and μd= 0.3 and find the minimum inclination that will ensure that a crate slides off an inclined plane. Find the value of the crate's constant acceleration. compare and verify your result with the analytical solution.
3. For the previous part, simulate the model for an end time of 0.5 seconds and plot the create acceleration vs. time. Show all the calculations and results clearly.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

What precautions should you take to prevent injuries when dealing with heavy loads?

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
