What is the equation for effort?
Effort X Effort Distance = Load X Load Distance
E X ED = L X LD
What’s the equation for mechanical advantage?
MA = (L/D) or (ED/LD)
What are the different classes of levers?
Check pg 230
What’s the equation for finding effort on an inclined plane?
Effort X length of plane = load X height
E X LP = L X H
What is the equation for mechanical advantage for and inclined plane?
MA = (length/height) or ED/height
What is the effort equation for a screw?
Effort X screw circumference = load X pitch
What’s the mechanical advantage equation for a screw?
MA = load/effort or circumference/pitch
What’s the equation for finding effort in a jack screw?
Effort X effort circumference = load X pitch
What’s the mechanical advantage equation for a jack screw?
MA = load/effort or handle circumference/pitch
What is the equation for mechanical advantage for and inclined plane?
MA = (length/height) or ED/height
What is the effort equation for a screw?
Effort X screw circumference = load X pitch
What’s the mechanical advantage equation for a screw?
MA = load/effort or circumference/pitch
What’s the equation for finding effort in a jack screw?
Effort X effort circumference = load X pitch
What’s the mechanical advantage equation for a jack screw?
MA = load/effort or handle circumference/pitch
What is the ratio of a pulley to a weight?
1 string = 1:1 as in one string lift the whole weight.
2 strings = force is cut in half. Example: in order to lift 5 lbs you would need 2.5 lbs of force.
3 strings = force is a third.
When the driver is larger than the follower what happens to the gears speed and torque?
The speed of the follower is greater then the driver.
The torque of the follower is less.
What happens to the gear speed and torque when the driver is smaller than the follower?
The speed of the follower is less than the speed of the driver.
The torque of the follower is greater.
What is the mechanical advantage of gears?
MA = teeth in driver/teeth in follower
What is the mechanical advantage of belt drives?
MA = diameter of driver/diameter of follower
