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)

Agas contained in a piston-oylinder assembly is initially at p1=100 ibf/ft^2? and occupies a volume of 3.75 ft. the gas is compressed to a pressure p2=500 ibf/ft^2 and a final volume of 0.5 ft. during the process, the relationship between pressure and volume is given as p= a +bv, where a and b are constants a)-determine the values and units for a and b b)-determine the volume, in ft, at an intermediate state where the pressure is 300 ibt/t2.

Design a quick return four bar mechanism that will have time ratio of tr 1: 1.25 . the output link should scan 60° angle for a full crank rotation . the length of output link is 5.0 em 1)-find the length of the other links and draw the mechanism .(write down your steps) 2)-does the mechanism satisfy the grashof's condition. 3)-find the max and min transmission angles over the range of motion using graphical technique
