Hello FI8D!
In this blog I will be talking to you about two different simple machines.
(FOR LEVERS REFER TO A BLOG POSTED 2 WEEKS AGO)
The Wedge:
The wedge is similar to an inclined plane but is of course different. A wedge is usually used to keep something in place or separate two different objects. A door stopper is a wedge because it keeps a door from moving.
How do you find the MA of a wedge? divide the slopes length by its length at the end that is thickest.
The Pulley:
Do you remember when you were little, and maybe had a tree house? Well for me I would take a rope, attach something like a sandwich to the end of it and pull it up into my tree house, but a pulley is slightly different because instead of pulling the rope yourself you have to install a fixed pulley which is a way of saying a circle with a piece of metal that is attached.
If you are having trouble visualizing GOOGLE: FIXED PULLEY and it will be very easy to find on google images.
