A seesaw is a specific type of lever; it consists of a long beam attached to a pivot called the fulcrum. As soon as you put weight on one end by sitting on one side of the beam it drops to the ground. This is because the force of gravity is acting on the weight of your body, pulling it and the beam down.Dec 13, 2018

Some examples of the wheel and axle include a door knob, a screwdriver, an egg beater, a water wheel, the steering wheel of an automobile, and the crank used to raise a bucket of water from a well. When the wheel in a wheel and axle machine is turned, so is the axle, and vice versa.
Carl Sjogreen started teaching coding at a summer camp while he was still in middle school. “I’ve had two passions my entire life, one is technology and one is education” the Seesaw founder tells me. But tech took over.
To calculate MA of a seesaw you need to multiply the Effort Force and Resistance Force or in the case of a seesaw or any lever Effort Distance and Resistance Distance.

Screws can be used to lift things or to hold them together. Examples of the screw simple machine include swivel chairs, jar lids, and, of course, screws.
I was shocked today to find out Seesaw does not allow a video attachment of longer than 5 minutes!
There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied. The wheel and axle is a machine in which the wheel is attached to a central axle.
Threaded fasteners are strongest in tension (being pulled apart) not in shear (slide apart). As a result, they prevent parts from sliding relative to each other by their clamp force not from the body of the fastener acting like a pin. What is the Difference Between a Bolt and Screw?
