Question

20 N effort is used in the 20 cm long spanner to unscrew a nut , then calculate momentum to unscrew the nut .
​

Answer 1

Answer:

In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. Wikipedia

SI unit: kilogram meter per second kg⋅m/s

Other units: slug⋅ft/s

Common symbols: p,

Answer 2

Answer:

Answer of Question...

Explanation:

Here, we are given, effort as 20 N and moment arm as 20cm,

Then, 20cm = 20/100 m = 0.2m

Now, Force = 20 N

Also, Moment  = Force x distance

                        = 20 x 0.2 Nm

                        = 4Nm

Therefore, the moment is 4Nm.
