What else can I help you with?
A machine that changes only the direction of a force has a mechanical advantage of?
1
How many times a force is multiplied by a machine is the machanical?
The mechanical advantage.
A pneumatic device is a machine that derives its mechanical advantage from what?
compress air
What can be done to increase the efficiency of the machine?
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.
The simple machine that provides a mechanical advantage of one?
Single fixed pulley
The mechanical advantage of a machine is always greater than 1?
well the advantage of that is pie, not math pie but pie that you eat
How many time a force multiplied by a machine is the mechanical?
Mechanical Advantage
What type of machine advantage describes the ability of a machine to increase output force?
mechanical advantage
What is the ratio of output force to input force of a machine?
That's the machine's "mechanical advantage".
If the output force is less than the input force of a simple machine the mechanical advantage less than one?
it means the mechanical advantage is greater.
If the input force is less than the input force of a simple machine the mechanical advantage is less than one?
it means the mechanical advantage is greater.
What is true about the mechanical advantage of a machine a it increases with greater friction b it decreases as the input distance increases c it is less than the idle mechanical advantage?
c) It is less than the idle mechanical advantage. The actual mechanical advantage of a machine is always less than the ideal mechanical advantage due to factors like friction and energy losses in the system.
How many times a force is multiplied by a machine is the mechanical what?
The number of times a force is multiplied by a machine is known as mechanical advantage. It is calculated by dividing the output force of the machine by the input force applied to it. A mechanical advantage greater than 1 indicates that the machine multiplies the input force.
True or False Finding the ratio of input force to output force gives you the mechanical advantage of a machine?
True. The mechanical advantage of a machine is determined by the ratio of output force to input force. A mechanical advantage greater than 1 indicates that the machine amplifies force, making it easier to do work.
What does it mean to say that a machine has a certain mechanical advantage?
When a machine has a certain mechanical advantage, it means that it can multiply the input force applied to it. Mechanical advantage is calculated as the output force divided by the input force required to lift a load. Machines with a mechanical advantage greater than 1 make it easier to lift heavy objects.
Why are speed ratio and mechanical advantage never the same?
Speed ratio and mechanical advantage are not the same because they are inversely related. Speed ratio is a measure of how much the input speed is amplified or reduced by a machine, while mechanical advantage is a measure of how much the input force is amplified or reduced. A machine that increases speed will have a mechanical advantage less than one, while a machine that increases force will have a mechanical advantage greater than one.
A lever with a mechanical advantage greater than one is used to do what?
A lever with a mechanical advantage greater than one is used to increase distance. A lever is a simple machine connected to ground by a hinge called a fulcrum.
