Answer:
The correct answer is 231 Mpa i.e option a.
Explanation:
using the equation of torsion we Have
where,
= shear stress at a distance 'r' from the center
T = is the applied torque
= polar moment of inertia of the section
r = radial distance from the center
Thus we can see that if a point is located at center i.e r = 0 there will be no shearing stresses at the center due to torque.
We know that in case of a circular section the maximum shearing stresses due to a shear force occurs at the center and equals
Applying values we get
Answer:
Convection is heat transfer through the movement of liquids and gases.
Inertia is the correct answer!
To analyze the differences in acceleration of the two objects, a necessary formula/relation to remember here is force = mass * acceleration. Given the different data in the problem, we can solve for the acceleration of each object. This is shown below:
Force = 15 N
M1 = 25 kg
M2 = 50 kg
a1 = ?
a2 = ?
For object 1:
15 N = 25 kg * a
a = 0.6
For object 2:
15 N = 50 * a
a = 0.3
Therefore, the acceleration of Object B is half that of Object A.
