The amount by which a machine multiplies an input force is called?
mechanical advantage
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
What does IMA stands for in physics?
ideal mechanical advantage
How does the mechanical advantage with input and output distance compare with the mechanical advantage using input and output force for the incline plane?
Mechanical advantage of an inclined plane: Ratio of force overcome by nature of weight of mass ( mass * acceleration due to gravity) to force required to move it. Example: ( take g as 10 (m/s)/s ) A mass of 10 kg is on a 30 degree incline , which generates (10 * 10) 100 newtons vertically down, the vector of this parallel to and down the slope is 100 * sin 30 degrees = 100 * 0.5 = 50 newtons which is the force required by the input force, so the ratio = 100:50 = 2:1 which is the mechanical advantage. This is also the ratio of vertical distance travelled by load : distance travelled up the slope
How does mechanical advantage differ from ideal mechanical advantage?
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
The ideal mechanical advantage for an inclined plane is equal to the length of the incline divided by the?
Ideal Mechanical Advantage for an Inclined Plane is equal to the length of the incline divided by the height of the incline.
What is the relationship between the angle of incline and mechanical advantage?
hj
What are the fomulas for incline plane?
( Assuming mass of object on incline plane is in kilograms (kg) ) . Force pulling down incline on object (kilogram force) = object mass * sin (incline angle) . Force of object acting on and normal to incline (kilogram force) = object mass * cos (incline angle) . Mechanical Advantage = 1 / ( sin ( incline angle ) )
What is the mechanical advantage of an incline plane?
MA of inclined plane:Distance moved parallel to slope / vertical distance moved:Reciprocal of sin of incline angle (from horizontal):1 / ( sin ( incline angle ) )
Does the mechanical advantage MA depend on the actual mass lifted through the incline?
no the mechanical advantage does not depends on the mass of the object lifted throgh inclined plane because if we increase the mass then we have to increase the force to pull the object up and the ratio will remain same.
Which is better a incline plane or pulley?
A single pulley simply changes the direction of the force. A block and tackle or multiple pulleys can offer a mechanical advantage - same as an inclined plane. For the same mechanical advantage, a pulley system may be better because of lower friction.
What are the functions of an incline plane?
Allows mechanical advantage, > Output force = Input force * (distance travelled up and parallel to ramp / vertical distance travelled)
What is the IMA of the inclined plane?
The ideal mechanical advantage, or IMA, of an inclined plane is equal to the length of the incline divided by its height. The IMA is calculated without regard to friction.
What is a mechanical adventage?
Mechanical Advantage;The ratio of load and effort is called mechanical advantage of any machine.Mathematical Formula Of Mechanical AdvantageMechanical Advantage = Load / EffortUnit Of Mechanical AdvantageAs mechanical advantage is the ratio of two forces, therefore it has no unit.
How does actual mechanical advantage compare with ideal mechanical advantage?
The actual mechanical advantage is usually less, due to losses.
What is the mechanical advantage of a ramp What is the mechanical advantage of a ramp standing straight up?
The mechanical Advantage is FORCE TIMES DISTANCE
The amount by which a machine multiplies an input force is called?
mechanical advantage
