Say you have a turbine that you need to spin the blade, how much does a 100lb weight produce in ft/lbs?

iF A TURBINE BLADE LENGH=10 FT,AND YOU ARE SETTING 100lbs.ON IT ,
IT WILL PRODUCED 1000FT/LBS.

The energy produced by a 100 lb weight is its weight times gravity times the distance it falls. So if it falls 2 ft, it produces 200 ft*lb.

The foot-pound force (symbol: ft·lbf) is an English unit of work or energy. To calculate a foot-pound force, you can use this formula:
W = F · d
Where W is work, F is force, and d is distance over which the force is applied (measured in the direction of the force).
The foot-pound force is also the English unit of torque, which is conventionally expressed in SI units as newton metres rather than joules. As a unit of torque, the order of the units is sometimes reversed, to distinguish from the energy units: pound force-foot (lbf·ft).
