Engineering >> Mechanical EngineeringCalculating Work Done to Pull Coal Out of a Mine Shaftby Tyler MacDougall
Submitted : Fall 2013 I calculated the work done to pull a 2lb/ft. cable and 800 lb. of coal 500 feet up. I set up an integral with bounds zero to fivehundred. I put the function for which the rate of work is changing 18002xdx, inside of the integral. Then, I antidifferentiated to get the function, the total work done. Then, I plugged in the values of my bounds, and I subtracted the lower bound from the upper bound. The total work done would be 650,000 ftlb. This job would require machinery.
