User: in a complete swing of a simple pendulum is there work done by the suspension string?

Weegy: Forces are air resistance (friction in the air), atmospheric pressure (an atmosphere at sea level, which lessens at higher altitudes) and friction at the point where the top of the wire is connected. [ When he studied the pendulum, Galileo discovered that it would swing on a regular basis. Its swing, called its period, could be measured. The length of the wire in general didn't change the period of the pendulum. ]

No, in a complete swing of a simple pendulum, there is no work done by the suspension string because the force is perpendicular to the direction of motion.

The efficiency of a simple machine, expressed as a ratio, is the actual mechanical advantage divided by the ideal mechanical advantage, reflecting how effectively the machine transforms input force into useful work.

define the efficiency of a simple machine in terms of actual mechanical advantage and ideal mechanical advantage?
Weegy: The first equation shows that the force exerted IN to the machine multiplied by the distance moved IN will always be equal to the force exerted OUT of the machine multiplied by the distance moved OUT. [ For example, using a block and tackle with 6 ropes, and a 600 pound load, the operator would be required to pull the rope 6 feet, and exert 100 pounds of force to lift the 600 pound load 1 foot. The second equation is a simplified formula based just on the forces in and out. Using the example above, 100 pounds of force IN results in 600 pounds of force OUT, an MA of 6. Both of these equations calculate only the ideal mechanical advantage (IMA) and ignore any losses due to friction. The actual mechanical advantage (AMA) includes those frictional losses. The difference between the two is the mechanical efficiency of the system. ] User: is it possible for a simple machine to multiply both force and speed at the same time? (More)

No, a simple machine follows the principle of mechanical advantage, where it can either multiply force at the expense of speed or multiply speed at the expense of force, but not both simultaneously.
