SRB Q1

Question 1

is a branch of mechanics which studies the effects and distribution of forces of rigid bodies which are and remain at rest

Answer 1

Statics

Question 2

is the physical science which deals with the effects of
forces on objects

Answer 2

mechanics

Question 3

primarily concerned to system of forces applied to body at rest.

Answer 3

statics

Question 4

is the study of body in motion

Answer 4

dynamics

Question 5

is the action of one body on another

Answer 5

force

Question 6

tends to move a body in the direction of its action.

Answer 6

force

Question 7

are those which are applied to the boundary of a structure. This
includes explicit externally applied forces as well as the forces that are applied by the supports to restrain the structure.

Answer 7

external forces

Question 8

are those that are exerted on a portion of a structure by the rest of
the structure. You would only see these forces if you were to make a cut in the structure and separate it into two free body diagrams

Answer 8

internal forces

Question 9

is a body of negligible dimensions. It is a
body whose dimensions are considered to be near zero so that we may analyze it as a mass concentrated at a point.

Answer 9

particle

Question 10

when the change in distance between any two of its points is negligible for the purpose at hand

Answer 10

rigid body

Question 11

are those with which only a magnitude is associated

Answer 11

scalar quantities

Question 12

are those possess direction and magnitude, and must obey the
parallelogram law of addition as described later in this article

Answer 12

vector quantities

Question 13

A force may be moved anywhere along its line of action without changing its external effects on a rigid body

Answer 13

PRINCIPLE OF TRANSMISSIBILITY

Question 14

is the measure of the capacity or ability of the force to produce twisting or
turning effect about an axis

Answer 14

moment

Question 15

The moment produced by two equal, opposite, and non collinear forces is called a

Answer 15

couple

Question 16

is a system of forces whose magnitude of the resultant is zero and yet
has a moment sum

Answer 16

couple

Question 17

refers to the number of forces which remain in same plane

Answer 17

coplanar force

Question 18

is a group of forces of which all are on the same
plane, and all forces intersect in a single common point.

Answer 18

concurrent force system

Question 19

is the simplest force combination which can replace
the original forces without altering the external effect on the rigid body to which the forces are applied.

Answer 19

resultant of a system of forces

Question 20

refers to the number of forces which are parallel to
each other with their lines of action.

Answer 20

parallel coplanar force system

Question 21

states that the moment of a force about a point is equal to the sum
of the moments of the components of the force about the point.

Answer 21

Varignon’s theorem

Question 22

refer to the number of forces which are not parallel and do not lie at the common point with their lines of action.

Answer 22

Non-concurrent and non-parallel coplanar force systems
