False,
Unless it is a twisted pulley system.

In which type of lever is the direction of the input force opposite of the direction of the output force?
That's a Class-1 lever, where the input and output are on opposite sides of the fulcrum.
Is work output always equal to work input?
Yes the only thing a machine changes is force,distance or direction
A force has both what?
A force is a vector quantity because it has both magnitude and direction.
Is it true that work output of a machine is always less than work input because of energy lost due to friction?
Yes this it true, because a percent of the input energy is converted to heat, which causes the output to became less than the input.
What causes the output work of a machine to be less than the input force?
Some of input energy is wasted in heating up the molecules, sound,etc therefore the resultent output work is always less than the input force due to loss of energy.
In which type of lever is the direction of the input force opposite of the direction of the output force?
That's a Class-1 lever, where the input and output are on opposite sides of the fulcrum.
Does a first class lever change the direction of the force?
yes it changes the direction, and increases the force
Can you get -5Volts as output when polarity is reversed?
yes.you can get 5v output even when the polarity is reversed. In a 5v battery, if u reverse the polarity, then u'll get the same 5v as output , but in the opposite direction.(i.e.,)-5v(negative 5 volt
What is the difference between an alternator and a magneto?
Difference Between Alternators and MagnetosAn alternator puts out alternating current [AC]. That means that part of the time electrons flow in one direction in the wiring, and part of the time the electrons flow in the opposite direction. The number of times the direction of current flow changes direction is referred to as "cycles."Even though the output of a magneto may be in pulses, the direction of flow of electrons is always in the same direction and is Direct Current [DC].
Is work output always equal to work input?
Yes the only thing a machine changes is force,distance or direction
What is the mechanical advantage of a machine that changes only the direction of applied force?
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
What is the mechanical advantage is a machine that changes only the direction of the applied force?

Does a pulley system cause the direction of the output force to be opposite to the direction of the input force?
A pulley system may cause the direction of the output force to differ from that of the input force, but is not guaranteed to do so. In a simple example, a double pulley could easily result in input and output forces in parallel.
How can you modify gear trains to reverse the direction of motion of the output shafts?
use a 3 bevelled gear arrangement akin to what is used in a car differential on the drive axle - it is possible to have a connecting shaft rotating the opposite direction to the original motion of the gears
What is the opposite of input?
Output. For example, if you input '2 + 2 =' in a calculator, the 4 that appears is the output.
Why terminals of opamp are called as inverting and noninverting?
In an op-amp, an input on the inverting terminal drives the output in the opposite direction, while an input on the non inverting terminal drives the output in the same direction. In a normal closed loop negative feedback configuration, there is feedback from output to inverting input, so that the output becomes a known function of input. So long as you stay within limits, the output will go to whatever value is required to make the inputs be the same.
A force has both what?
A force is a vector quantity because it has both magnitude and direction.
