What is a single fixed single movable effort up?
it uses 2 pulleys workinf together !! hailey
How do you calculate the mechanical advantage of gears?
effort divided by load or vice versa
What type of pulley can you use to change the direction of the effort force?
Fixed Pulley and Compound Pulley.
Using a crowbar you apply an effort force of 30 N to pry open a window that has resistance force of 600 N so What is the mechanical advantage MA of the crowbar?
MA= Resistance force / Effort force = 600N / 30 N MA = 20N
What is a second class lever?
A Class 2 lever has the load in-between the effort and the fulcrum. An example is a wheelbarrow, Effort is at the handles, the wheel is the fulcrum, and load is the weight carried on the wheelbarrow.
How is IMA determined for pulleys?
IMA for pulleys is the resistance force divided by the effort force.
What type of pully can multiply effort force?
Actually, pulleys cannot multiply effort force. It can only change the direction of the effort force.
How can you increase a pulleys mechanical advantage?
By increasing the effort distance on the machine.
A system of pulleys designed to multiply the effort force is called a what?
moveable pulley
What is a system of pulleys designed to multiply the effort force called?
moveable pulley
How are belts and pulleys similar?
They are equivalent because they are both pulling something with effort on each end.
What are simple machiens?
simple machiens are the thing which reduce human effort
What is a single fixed single movable effort up?
it uses 2 pulleys workinf together !! hailey
How pulley systems work?
Ropes or cables run around pulleys and each pulley wheel reduces the pulling effort.
Which pully would require more effort force?
Not entirely sure what you mean but maybe this will help: In general the more pulleys you have in your system the less force you will need to apply to lift a certain load, in this case the system of pulleys is generally called a "block and tackle".
What is the disadvantage of pulleys?
movable pulleys sometimes don't have a directional advantage so you have to pull up and you can't use a weight as the effort and whoever said this its wrong so next time USE THE TEXT BOOK STUPID PERSON sorry about this my friend can be mean.
How do pulleys make work better?
Well, since a pulley is a SIMPLE machine it makes work better because all you have to do is put effort to a pulley instead of using your hands
