Therr workers trying to move a 1x1x1.2-m crate apply to the cratethe three horizontal forces shown. (a) if P=240 N, replace the

threeforces with an equivalent force-couple system at A. (b)

Replace theforce-couple system of part a with a single force, and

determinewhere it should be applied to side AB. (c) determine the

magnitudeof P so that the three forces can be

replaced witha single equivalent force applied at B.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
