Question

Example 4. Charles applies an effort of 40 N on a simple machine through a distance of 1.5 m is able to push a load of 100 N through a distance of 30 cm. Find the input, output and efficiency of a machine. through which effort is applied - 1​

Answer 1

Answer:

thnx frnd for your support study

Answer 2

Answer:

Output of machine is 30 Nm. , input  is 60 Nm. and efficiency is 50%

Explanation:

Given:

Effort = 40 N

Distance = 1.5 m.

Input = effort × Distance

         = 40 × 1.5 =60 N-m.

Weight of load = 100  N

Distance = 30 cm. =30/100=0.3 m.

Output = Weight of load × distance

            = 100 × 0.3 = 30 N-m.

Efficiency = (output /input ) × 100

                 = (30 / 60 ) × 100 =50 %
