Explore the full setState the meaning of a machine.
Answer
A machine is a device by which a large resistive force called the load can be overcome at some point by applying a small force called the effort at a convenient point and in a desired direction, or by…
What is the difference between load and effort?
Answer
Load is the resistive force overcome by the machine. Effort is the force applied to the machine to overcome the load. In a simple example, the load is the heavy object and the effort is the force used…
When does a machine work as a force multiplier?
Answer
A machine works as a force multiplier when mechanical advantage is greater than 1, so load is greater than effort. In that case, a small effort can lift a larger load.
When does a machine give gain in speed?
Answer
A machine gives gain in speed when effort is greater than load. In this case, mechanical advantage is less than 1, so the machine helps movement at the cost of force.
State the definition of velocity ratio.
Answer
Velocity ratio is the ratio of velocity of effort to velocity of load. Formula: V.R. = Velocity of effort / Velocity of load It also equals the ratio of displacement of effort to displacement of load.
A machine has effort velocity 8 m/s and load velocity 2 m/s. Find the velocity ratio.
Answer
Given: Velocity of effort = 8 m/s, Velocity of load = 2 m/s Formula: V.R. = Velocity of effort / Velocity of load Step 1: V.R. = 8 / 2 Step 2: V.R. = 4 Answer: Velocity ratio = 4, no unit…
If a machine moves effort through 12 m and load through 3 m in the same time, find the velocity ratio.
Answer
Given: dE = 12 m, dL = 3 m Formula: V.R. = dE / dL Step 1: V.R. = 12 m / 3 m Step 2: V.R. = 4 Answer: Velocity ratio = 4, no unit…
State the definition of efficiency.
Answer
Efficiency is the ratio of useful output work to input work. Formula: η = Woutput / Winput × 100% Unit: no unit, because it is a ratio of two similar quantities. It is usually written in percent.
