Question on: JAMB Physics - 2024
An effort of 40 N is applied on a machine to lift a mass of 60 kg. Determine the mechanical advantage of the machine [g = 10 m/s²]
A
2400
B
240
C
150
D
15
Ask EduPadi AI for a detailed answer
Correct Option: D
1. Calculate the load (output force): W = m g = 60 kg * 10 m/s² = 600 N
2. Calculate the Mechanical Advantage (MA): MA = Load / Effort = 600 / 40 = 15
