PAPER 2026 QUESTIONS WITH 100%
CORRECT ANSWERS
◉ Mechanics of Rigid Bodies Answer: Statically deals with the
equilibrium of bodies, that is those that are either at rest or move
with a constant velocity.
◉ Dynamics Answer: Concerned with the accelerated motion of
bodies.
◉ Length Answer: Used to describe the position of a point in space
and thereby describe the size of the physical system.
◉ Time Answer: Conceived as a succession of events.
,◉ Mass Answer: A measure of a quantity of matter that is used to
compare the action of one body with that of another.
◉ Force Answer: Considered as a 'push' or 'pull' exerted by one body
on another, characterized by its magnitude, direction, and point of
application.
◉ Weight Answer: The force acting on an object due to gravity,
calculated as mass multiplied by gravitational acceleration.
◉ Scalar Quantity Answer: A positive or negative number; e.g., mass
and temperature, magnitude of a force.
◉ Vector Quantity Answer: Has a magnitude and direction, where
the arrowhead represents the sense of the vector.
◉ Particle Answer: A particle has a mass, but has a size that can be
neglected.
◉ Rigid Body Answer: Considered as a combination of a large
number of particles in which all the particles remain at a fixed
distance from one another.
,◉ Concentrated Force Answer: Represents the effect of loading
which is assumed to act at a point on a body.
◉ S.I UNITS Answer: The International System of units defining
length in meters (m), time in seconds (s), and mass in kilograms
(kg).
◉ Newton (N) Answer: The base measure of a force in S.I. notation.
◉ Pound-force (lbf) Answer: The base measure of a force in Imperial
units or English Customary Units.
◉ Pascal Answer: The measure of pressure in S.I. units (equivalent
to N/m2).
◉ Equilibrium of a Particle Answer: When a particle is at rest or
moves with constant velocity, requiring that all the forces acting on
the particle form a zero resultant force.
◉ Equilibrium of a Body Answer: A body in equilibrium is at rest or
can translate with constant velocity, with net forces and net moment
being zero.
, ◉ Resultant Force Answer: Forces which are spread out over a
length, area, or volume.
◉ Center of Gravity Answer: The point where all of an object's
weight may be concentrated and still have the same external effect
on the body.
◉ Force Distribution Answer: refers to how forces are spread out or
transferred
◉ Free-Body Diagram Answer: a simplified visual representation of
an object (or 'body') showing all the forces acting on it, without its
surroundings, using vectors to depict the forces' magnitudes and
directions.
◉ Moment Answer: also known as moment of a force. In mechanics,
moment is defined as the tendency for a body to produce a rotation
about a point that is not on the line of action of its force. Moment is
defined as directly proportional to the magnitude of the force and
the perpendicular distance or moment arm.
◉ Moment Arm Answer: is the perpendicular distance of a force
from a point of interest.
