A bolt is to be tightened with a torque of 7.0 N · m. If you have a wrench that is 0.55 m long, what is the least amount of forc
kodGreya [7K]

To solve this problem we will apply the given concept for torque which explains the relationship between the force applied and the distance to a given point. Mathematically this relationship is given as

\tau = F*d \rightarrow F = \frac{\tau}{d}

Where,

\tau = Torque

F = Force

d = Distance

Our values are given as,

\tau = 7.0Nm , d = 0.55m

Therefore replacing we have that the force is

F = \frac{7}{0.55}

F = 12.72N

Therefore the least amount of force that you must exert is 12.72N

An object on Earth's surface has a weight of 609 N. What is its mass?
mars1129 [50]

Answer:

62.1 kg

Explanation:

Weight = mass × acceleration

609 N = mass × (9.8)

The acceleration is 9.8 because that is the acceleration of gravity.

Divide both sides by 9.8 to isolate the mass.

609N/9.8 = mass

62.1 kg =mass

mg = 12000 N
cos10°= 0.984
thus it will be 12000*0.984 = 11808N
the frictional force will be
