Question

A nut is opened by a rench 20cm.If the least force required is 2N.finf the moment of force needed to loosen the nut​

Answer 1

Answer:

answer is 0.4 NM

According to the principle of moments we have Moment of load about the fulcrum = Moment of effort about the ful crum Load x Load arm = Effort x Effort arm Given that the effort arm = 20cm = 0.2m the minimum force E = 2N Therefore the moment of load or the moment of force = 0.2 93 Work Power and Energy x 2 = 0.4Nm The moment of force needed to loosen the nut = 0.4Nm
