what is the resistance offered by nut
Asked by suneelmsc | 14 Jul, 2020, 03:04: PM
Expert Answer
The effort required to crack a nut is 0.5 N, then the resistance offered by the nut is _______
E = 0.5 N
Effort arm = distance between the fulcrum and the effort = 2+ 18 = 20 cm
Load = Resistance offered by the nut =?
Load arm = 2 cm
We know, the principle of lever,
Effort x Effort arm = Load x load arm
Thus,
0.5 N x 20 cm = L x 2
Thus,
Thus, the resistance offered by the nut will be 5 N
correct option - (B) - 5 N
