Which of the following is the correct expression according to parallel axis theorem used for finding moment of inertia of plane figures?
Where,
'I1-1' is the moment of inertia of plane figure about an axis 1-1 which not passing through centroid of plane figure.
Ix-x is the moment of inertia of plane figure about an axis x-x passing through centroid which is parallel to axis 1-1
A is the area of considered plane figure
h is the perpendicular distance between axis 1-1 and axis x-x.
I1-1 = Ix-x<sup>2</sup> + Ah2
I1-1 = Ix-x2 + A2h
I1-1 = Ix-x + A2h
I1-1 = Ix-x + Ah2
Correct answer
I1-1 = Ix-x<sup>2</sup> + Ah2

Identify incorrect statement with respect to crossbelt drive used to transmit power from one shaft to another.
Since power transmitted by this type of belt drive is due to the friction, belt drive is subjected to slip and creep.
In case of cross belt drive, belt wears very fast.
In case of cross belt drive, the angle of contact of belt on both the pulleys is equal.
In case of cross belt drive, the pulleys rotate in the same direction.
Correct answer
Since power transmitted by this type of belt drive is due to the friction, belt drive is subjected to slip and creep.
Consider the below statements with respect to work and power and identify correct answer.
Statement A : The product of the displacement and the component of force in the direction of displacement is referred to as work done.
Statement B : Power has direction component as it is a vector quantity.
Statement A is correct and B is incorrect
Both statements are correct
Statement B is correct and A is incorrect
Both statements are incorrect
Correct answer
Statement A is correct and B is incorrect
Which of the following is not the property of an equipotential surface?
The electric field is always parallel to an equipotential surface
The spacing between equipotential surfaces helps to identify regions of weak fields
The spacing between equipotential surfaces helps to identify regions of strong fields
Work done in moving a charge over an equipotential surface is zero
Correct answer
The electric field is always parallel to an equipotential surface
