A non-sinusoidal voltage is v(t) = 5 + 10 * sin(2π * 50t + 30 ) 15sin(4π 0t 45 ) . o + * 5 + o This voltage is connected to the load which is a serial connection of a 10Ω resistor and a 10mH inductance. Determine: a) the power absorbed by the load, and b) Drive an expression for the load

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way
