Question
Download Solution PDFIn a lifting machine, an effort of 500 N is to be moved by a distance of 20 m to raise a load of \(10,000 \text{N}\) by a distance of 0.8 m . Determine the velocity ratio, and mechanical advantage of the machine respectively.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
In lifting machines:
-
Velocity Ratio (VR) = Distance moved by effort / Distance moved by load
-
Mechanical Advantage (MA) = Load lifted / Effort applied
Calculation:
Given:
-
distance moved by effort = 20 m
-
distance moved by load = 0.8 m
-
Load = 10,000 N
-
Effort = 500 N
Velocity Ratio (VR) = 20/0.8 = 25
Mechanical Advantage (MA) = 10000/500 = 20
