FOOT SWITHCES LT-4 LB

It looks like you’re asking about the meaning of “foot-pounds” (ft-lb) and “pound-feet” (lb-ft). These terms are often used interchangeably, but they actually refer to different concepts:

1. Foot-Pounds (ft-lb): This is a unit of work or energy. It measures the amount of energy required to move a one-pound object one foot of linear distance. For example, if you lift a one-pound weight one foot off the ground, you have exerted one foot-pound of energy.

2. Pound-Feet (lb-ft): This is a unit of torque, which is a measure of rotational force. It is the force of one pound acting on a lever arm one foot long. For instance, when you use a wrench to tighten a bolt, the torque applied is measured in pound-feet.
