The pulley allows the re-direction of force by 180 degrees. A ramp cannot do that. Say you need to lift an engine out of a car's engine bay. You would use a pulley because as you pull straight down the engine goes straight up. That presumes that you weigh more than the engine.

Why is a ramp better than a ladder and what are the disadvantages of the ramp?
A ramp is better than a ladder because it allows for easier movement of wheeled objects like wheelchairs, carts, or strollers. However, ramps require more space to install compared to a ladder, and they are not suitable for situations where vertical height is limited. Additionally, ramps may be more expensive to construct than ladders.
Would a short or long ramp have a greater mechanical advantage?
There is a mechanical advantage in using a long, gently sloping ramp than a short steep ramp. If you want to test this remember what goes up must come down and a long ramp gives you more time to react
Why is a pulley a force multiplier?
A pulley is a force multiplier because it allows a person to lift a heavy object with less force than would be needed without the pulley. By redirecting the force needed to lift the object, a pulley system can increase the efficiency of the process and reduce the amount of force required.
What describes how the IMA of this ramp compares with the IMA of the ramp that has a height of 1m?
The ideal mechanical advantage (IMA) of a ramp is calculated as length divided by height. Therefore, the IMA of a ramp with greater height will be smaller than the IMA of a ramp with a height of 1m. This means that a taller ramp will require less effort but over a longer distance to overcome gravitational force compared to a ramp with a height of 1m.
In the picture below if pulley A is moved clockwise what direction and how fast will pulley C turn?
If pulley A is moved clockwise, pulley C will also turn clockwise at half the speed of pulley A due to the belt connection. This is because pulley C has a larger diameter than pulley A, causing it to rotate slower while maintaining the same linear speed.
Would a skateboard ramp have a greater slope than a handicap ramp?
yes
Are water pumps off a 1998 an 1994 dodge ram 1500 the same?
The 1994 would have a bolt on pulley while the 1998 had a pressed on pulley. Other than that they are same. A new pump would be of the pressed on pulley style.The 1994 would have a bolt on pulley while the 1998 had a pressed on pulley. Other than that they are same.

How can you decrease the effort needed to push a weight to the top of the ramp?
Lubricate the slope with grease (except where you would be walking, of course!), or put the weight on a wheeled trolley. You could also use a pulley system, but that would mean pulling the weight up, rather than pushing.
Is a halfpipe easier to skate than a mini ramp?
No, your better off starting on a 4 foot mini ramp. Perfect any moves before taking on a halfpipe.
Would you use a fixed pulley or movable pulley to lift a heavy load?
Fixed if it weighed as less than you, but a movable pulley wouldn't be helpful here. You'd be best with a pulley with multiple supporting ropes.
Is a zipper a lever pulley ramp screw wheel wedge?
A zipper is best classified as a type of mechanical fastener rather than fitting neatly into the categories of lever, pulley, ramp, screw, wheel, or wedge. However, it does function similarly to a wedge because the interlocking teeth of the zipper create a secure closure when pulled together. In essence, while it utilizes mechanical principles, a zipper is unique in its design and function.
If you have motor rpm motor shaft sizeblower pulley size how you get blower rpm?
Drive Pulley = pulley on motor Driven Pulley = pulley on blower First determine your Ratio - divide large pulley size by small pulley size this will give you gear ratio, Example 2" drive pulley and a 4" Driven Pulley = 2:1 gear ratio If you know your motor shaft RPM divide that number by the ratio to get the RPM of the driven pulley, if your shaft rpm is 1800 rpm you would divide 1800 by 2 which would = 900 rpm on your driven pulley if your drive pulley is larger than than your driven pulley you multiply the rpm by the ratio example 1800 rpm x 2 = 3600 rpm
Can the drive pulley be bigger than the driven pulley?
Yes.
How does the speed of a ball change with the different ramp surfaces?
It depends on the ramp surfaces because some ramp surfaces have less friction than others and some have more friction than others.
Why does a skateboard make a louder noise on a concrete ramp than a wooden ramp?
Concrete has a lot of creases and bumps and the wooden ramp is smooth
Can you use skateboard wax for a skimboard ramp wax?
I'm sure there are different kinds of wax that will work better than skate wax, but any wax is going to work better than none. So I say Yes, do it!
