Question

Numerical Problems
1. A load of 680N is lifted from A to C by 500N
force on an inclined plane as shown in the
diagram. Study the diagram and calculate:
i. Output work
ii. Input work
iii. Mechanical advantage
iv. Velocity ratio
V.Efficiency​

Answer 1

Answer:

here u go =)

Explanation:

 Output work  

Given

Load: 680  

Effort: 500  

Ed: 12 Meters  

Ld: 8 meters  

Output work formula

L*Ld = 680*8 = 5440

Hence output is 5440J  

Input work  

We know  

the input work formula is  

E*Ed

500*12  

6000J
