a fish exerts a 10-ib force on the line that is represented
bythe vector f. express f in terms of components using the
coordinatesystem.

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)

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Around steel bar, made from material with a yield stress of 750mpa, is loaded so that it has stresses co locations of maximum normal stress and maximum shear stress. use maximum shear stress and maximum distortion energy theories to calculate the safety factors for initial yielding failures.
