Mechanics of Engineering - Wednesday, 1st Period
“Good morning,” Goose began that week’s class, “so we’ve covered the pulley and the wheel and axel, this week our class is going to focus on the lever as our next simple machine,”
“The lever is a simple machine where a bar rotates around a fixed point fulcrum,” he explained, “a fulcrum is best described as the support for a bar,”
“There are three different types of levers,” he continued, “first, second and third class levers and the way that each one is classified is that they each have a different applied point - the effort, the load and the function,”
“Some examples of different levers are - pliers and scissors for first class levers, and going back to our lecture last week a wheelbarrow is also an example of a second class lever,” he added, “finally examples of a third class lever are barbecue tongues, a broom and a fishing rod,”
“For our practical today, we’re going to be looking at making levers,”
