Also another name for a pulley system is called a block and tackle.
Door Knob: A door knob is considered a wheel and axle because it contains a wheel that is attached to an axle that allows for the wheel to move and helps magnify the force you exert.
Ramp: A ramp is considered an incline plane because it permits you to overcome a large resistance, by applying a small force through a longer distance when raising the load.
Jack Screw: A jack screw is considered a screw because it contains a modification of an inclined plane and requires a force over a greater distance while exerting a greater force.
Car Transmission: A car transmission is considered a gear because it contains multiple gears that can apply force and power in different portions and directions.
9. A ½” wrench with a 6 inch long handle is used to install a lag bolt into the side of a deck. For every full turn of the wrench (360 Degrees), the lab bolt advances into the wood 1/8”.
a. What is the MA of the system
MA= R/E=L/l
MA= 6/.5= 12
b. How much force is exerted on the bolt if the input force is
