The magnitude of the vertical force W is 160 N. The direction cosines of the position vector from A to B are coso, = 0.500, cose,-0.866, coso, -0, and the direction cosines of the position vector from B to C are cos8, = 0.707, cose, = 0.619, cose, = -0.342. Point G is the midpoint of the line from B to C. 1. Show all the necessary F.B.D 2. Find out rAG 3. Determine the vector rAG X W, where rAG is the position vector from A to Ge 600 mm

There may or may not be one or more mistakes in the solution. Go through the solution carefully and then do the following. 1. State if the solution is correct or incorrect 2. If the solution is incorrect, identify what is the mistake in the solution. Be specific and succinct. 3. If the solution is incorrect, provide the final solution with appropriate steps. Problem: A refrigeration cycle uses refrigerant R-134a to cool down water from 40°C to 20°C. The refrigerant R-134a enters the cycle as saturated liquid at -15°C and exits as saturated vapor at the same temperature. The mass flow rate of R-134a is 0.12 kg/s. The overall heat transfer coefficient is 1400 W/m².K. The surface area of the heat exchanger is 1.4 m². What is the rate at which heat is being exchanged between R-134a and water? Assume that the heat exchanger is perfectly insulated from outside (i.e., there is no convection or radiation with the outside/surrounding). Solution: We know, from the definition of overall heat…

can you please provide the solution for the answer in Reaction Ay?

Q. Define : Mechanical efficiency.

When does force work?

What’s the correct answer please?

The solution (298.349) is incorrect as well.

Don't submit the wrong solution.

13. The amount of heat (Hth, thermal energy) stored in rocks, m = 500 kg, S = 840 J/(kg °C), Tfinal =50°C, Tinitial = 40°C is: ·Hth = 19*10E(6) Joules. ·Hth = 4.2 * 10E(6) Joules. %3D ·Hth = 4.2*10E(4)Joules. %3D
