Force Exe-1A Very Short Type Que
Concise Class 10 ICSE Selina Solutions
Que-1: State the condition when on applying a force, a body has:
A. translational motion
B. rotational motion.
Ans. (A). when a body is free to move. Then the transitional motion is produced.
(B). when the body is fixed at a point. The rotational motion is produced.
Que-2: State whether the moment of force is a scalar or vector quantity?
Ans. moment of force is defined as vector quantity.
Que-3: Write the expression for the moment of force about a given axis.
Ans. the moment of force is given by the
the moment of force a given axis= Force × perpendicular
distance of force from The rotation of axis.
Que-4: State one way to reduce the moment of a given force about a given axis of rotation.
Ans. decreasing the perpendicular distance of force from the axis of rotation. when The moment of force can be reduced.
Que-5: State one way to obtain a greater moment of a force about a given axis of rotation.
Ans. where increasing the perpendicular distance of force from the axis of rotation. then We can obtain a greater moment of force.
Que-6: Complete the following sentences:
(1). The S.I. unit of moment of force is ……………
(2). In equilibrium algebraic sum of moments of all forces about the point of rotation is …………….
(3). In beam balance when the beam is balanced in a horizontal position, it is in …………… equilibrium.
(4). The moon revolving around the earth is in ……………equilibrium
Ans. (1) moment of force SI unit is newton meter (NM).
(2) The sum of moment of all forces about the point of rotation is zero in equilibrium algebraic.
(3) When the beam is balanced in a horizontal position it is in static equilibrium.
(4) When the moon revolving around the earth is in dynamic equilibrium.
