Question

what is the efficiency of a machine that can carry a load of 100 kg with an effort of 20N when its velicity ratio is 10​ ASAP

Answer 1

Answer:

Efficiency of machine=4.9

Explanation:

We are given that

Mass of load=100 kg

Effort=20 N

Velocity ratio=10

We have to find the efficiency of machine.

Load=$mg=100\times 9.8=980 N$

Efficiency=$\frac{Load}{effort}\times \frac{1}{velocity\;ratio}$

Using the formula

Efficiency of machine=$\frac{980}{20}\times \frac{1}{10}$

Efficiency of machine=$\frac{49}{10}$

Efficiency of machine=4.9
