Answer:
0.301 m
Explanation:
Torque = Force × Radius
τ = Fr
40.0 Nm = 133 N × r
r = 0.301 m
The mechanic must apply the force 0.301 m from the nut.
Answer:
A-500 N
Explanation:
The computation of the tension in the chain is shown below
As we know that
F = ma
where
F denotes force
m denotes mass = 7
And, a denotes acceleration
Now for the acceleration we have to do the following calculations
The speed (v) of the hammer is
v = Angular speed × radius
where,
Angular seed = 2 × π ÷ Time Period
So, v = 2 × π × r ÷ P
v = 2 × 3.14 × 1.8 ÷ 1
= 11.304 m/s
Now
a = v^2 ÷ r
= 70.98912 m/s^2
Now the tension is
T = F = m × a
= 7 × 70.98912
= 496.92384 N
= 500 N
Answer:
Area = 20 m²
Explanation:
Given the following data;
Force = 2500 N
Pressure = 125 Pa
To find the area on which it rest;
Mathematically, pressure is given by the formula;
![Pressure = \frac {Force}{area}](https://tex.z-dn.net/?f=%20Pressure%20%3D%20%5Cfrac%20%7BForce%7D%7Barea%7D%20)
Making area the subject of formula, we have;
![Area = \frac {Force}{pressure}](https://tex.z-dn.net/?f=%20Area%20%3D%20%5Cfrac%20%7BForce%7D%7Bpressure%7D%20)
Substituting into the formula, we have;
![Area = \frac {2500}{125}](https://tex.z-dn.net/?f=%20Area%20%3D%20%5Cfrac%20%7B2500%7D%7B125%7D%20)
Area = 20 m²
