How much force will the operator have to apply if the mechanical advantage of the pulley system is 4?
1/4 the output force.
What is the mechanical advantage of a fixed pulley?
' 1 ' is.
How long is a ramp from the top of the pyramid to the ground that has a mechanical advantage of 4?
The height of the Great Pyramid = 139 metres The slope of a ramp with a mechanical advantage of 4 = 4x139 = 556m
When is mechanical advantage less than 1?
When the output is less than the input. Mechanical advantage is expressed as the ratio of the output to the input.
What class or classes of lever always have a mechanical advantage greater than 1?
A second class lever always has a mechanical advantage greater than 1.
A 1-cm screw with a 4-cm thread would have a mechanical advantage of?
4
What is the mechanical advantage for a bicycle?
Can't be answered. Different bikes have different gears, and with different gears come different mechanical advantage. A MTB can have an adjustable mechanical advantage ranging from 0.75:1 - 1:4
How much force will the operator have to apply if the mechanical advantage of the pulley system is 4?
1/4 the output force.
What is the ideal mechanical advantage of a machine that only changes the direction of the input force?
Mechanical Advantage=1
If the input force on a simple machine is 2 N and the output is 4 N what is its mechanical advantage?
1
What is the mechanical advantage of a ramp that is 8 m long and 2 m high porch?
The mechanical advantage is 8/2 = 4.
What is the mechanical advantage of a fixed pulley?
' 1 ' is.
Why can't a pulley have a mechanical advantage greater than 1?
The mechanical advantage of a pulley can be greater than 1.The efficiency cannot but that is a different matter.
What is maximum value of mechanical advantage?
Mechanical advantage is maximum when weight lifted is extremly high and for which C/W is extremely small so as to be negleted, Max. Mechanical Advantage=1/m
