A closed system of mass 6lbm undergoes a process in which there is a heat transfer of 245 ft-lbf from the system to the surroundings. There is no work during the process. The velocity of the system changes from 12.7 ft/s to 55 ft/s and the elevation decreases by 127 ft. The acceleration of gravity is 32.0 ft/s^2. Determine the change in internal energy of the system in ft-lbf and BTU.
We're asked to determine the deflection of a beam location for a 2000N load. However the force is directed up the corner NOT centroid.
A 12 Volt battery is charged by supplying 3 Amps over a period of 6 hours. What is the change of energy stored in the battery if the battery loses 400kJ of heat during charging.
Hydrostatic relation, An empirical formula relating pressure and density for seawater w/ temperature held constant is
The rigid L-shaped member ABC is supported by a ball and socket at A and by three cables. Determine the tension in each cable and the reaction at A caused by the 242 kg load applied at G.
Treat the locomotive as a particle and assume that the railroad tracks are rectilinear and horizontal.
Determine the angle theta degrees that requires the minimum torque T to keep the seam closed. (Hint: use Mohr's circle). Give the answer in degrees.
Consider a mass going through a polytropic process where pressure is directly proportional to volume (n=-1) the process starts with P=0,V=0 and ends with P=600kPa,V=0.01m^3. Find the boundary work done by the mass.
the manometer shown above in problem 1 above contains water and kerosene. with both tubes open to the atmosphere, the free surface elevations differ by H=20mm determine the elevation difference when a pressure of 98.0 Pa is applied to the right.
what would be the formula to find out weld pressure adjustments when atm inside the tube is changed?
the suspended load exerts a force F=600 lb at A, and the weight of the bar OA is negligible. Determine the tensions at the cables and the reactions at the ball and socket support O
Aim of this demonstration is to use measurements of the load required to propagate a crack (tear) in packaging tape to determine its fracture toughness and Describe the fracture behaviour of the insulation tape loaded with a small crack. Explain w..
