Which of the following is a scalar quantity?
Force
Speed
Velocity
Acceleration
The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction in which the force acts. This statement is known as
Newton's first law of motion
Newton's second law of motion
Newton's third law of motion
none of these
In a framed structure, as shown in the below figure, the force in the member AC is numerically equal to the force in member BC.
Correct
Incorrect
The above figure shows the three coplaner forces P, Q and R acting at a point O. If these forces are in equilibrium, then
The polygon law of forces states that if a number of forces, acting simultaneously on a particle, be represented in magnitude and direction by the sides a polygon taken in order, then their resultant is represented in magnitude and direction by the closing side of the polygon, taken in opposite direction.
Correct
Incorrect
A couple produces
translatory motion
rotational motion
combined translatory and rotational motion
none of the answers
The centre of gravity of a right angled triangle lies at its geometrical centre.
Correct
Incorrect
The moment of a force
is the turning effect produced by a force, on the body, on which it acts
is equal to the product of force acting on the body and the perpendicular distance of a point and the line of action of the force
is equal to twice the area of the traingle, whose base is the line representing the force and whose vertex is the point, about which the moment is taken
all of the answers
If three forces acting at a point be represented in magnitude and direction by the three sides of a triangle, taken in order, the forces shall be in equilibrium.
True
False
The moment of the force P about O as shown in the below figure is
P x OA
P x OB
P x OC
P x AC
