Question

In an inclined plane, an effort is applied to lift a load of

1000 N. The MA and VR of the incline plane are 2 and 3
respectively. Calculate the efficiency and effort applied.

Answer 1

To calculate the efficiency and effort applied, we can use the formulas:

Efficiency = (Output / Input) × 100%

Effort = Input / MA

Given:

Load (Output) = 1000 N

MA = 2

VR = 3

First, let's calculate the Input (Effort) using the formula:

Effort = Input / MA

Effort = (Load / VR) / MA

Effort = (1000 N / 3) / 2

Effort = 166.67 N

Next, let's calculate the Output:

Output = Load / VR

Output = 1000 N / 3

Output = 333.33 N

Now, we can calculate the Efficiency using the formula:

Efficiency = (Output / Input) × 100%

Efficiency = (333.33 N / 166.67 N) × 100%

Efficiency = 2 × 100%

Efficiency = 200%

Therefore, the efficiency is 200% and the effort applied is 166.67 N.
