Acantilever of length 0.5 m and square cross-section of sides 50 mm is subjected to a downward-acting alternating end load. the static tensile yield and fatigue strengths for completely reversed stress of the material are 300 mpa and 200 mpa. if the mean stress σm= 30 mpa, using the soderberg equation determine the maximum and minimum values of the end load. also show stress-time variation curve (sinusoidal).

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)
