The steel plate shown supports six 2 in diameter idler
rollersmounted on the plate as shown. two flat belts pass around
therollers, and rollers a and d are adjusted so that the tension
ineach belt is 10 lb. determine
a.) the resultant couple acting on the plate if a = 8in.
b.) the value of a so that the resultant couple acting on
theplate is 480lb. in clockwise.

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
