energy when compressed
And energy when they rebound.

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)

How much power could a wind turbine produce if it had the following specifications? cp = 0.45 -d=1.2kg/m3 d=50m v 5m/s

A)-explain briefly the importance of standards in engineering design. b)- what is patent? c)-explain the relationship between these standards: b. s. and b. s.en d)- in engineering design concepts, types of loads and how they act are important factors. explain.
