Which of the following has greatest mechanical advantage
Load=150N, EFFORT =25N
Load=685N, EFFORT =1235N
Load =147, EFFORT =30 N
Please answer
Answer B
Load 685N effort 1235 N
A load of mass 80kg was lifted a distance of 12m if the effort applied to lift the load was 60m to the height of 30m calculate the work output by a machine
To determine which of the given options has the greatest mechanical advantage, we need to calculate the mechanical advantage for each option. Mechanical advantage is calculated using the formula:
Mechanical Advantage = Load / Effort
Let's calculate the mechanical advantage for each of the options:
Option 1:
Load = 150N, Effort = 25N
Mechanical Advantage = 150N / 25N = 6
Option 2:
Load = 685N, Effort = 1235N
Mechanical Advantage = 685N / 1235N = 0.555
Option 3:
Load = 147N, Effort = 30N
Mechanical Advantage = 147N / 30N = 4.9
Based on the calculations, option 1 has the greatest mechanical advantage with a value of 6. Therefore, the answer is option 1: Load = 150N, Effort = 25N.
