Term
 False
Definition
 Statistics is a part of Statics
Term
 True
Definition
 In Statics, Space and Force are two major physical quantities, while time is not.
Term
 False
Definition
 There are ten major principles or laws applicable in Statics
Term
 False
Definition
 Principle of transmissibility deals with multiple forces acting on a particle
Term
 True
Definition
 In order to apply the third law of Newton there must be at least two bodies in contact.
Term
 True
Definition
 The law of addition of two forces allows us to replace the two forces acting on a body by only a single force called the resultant.
Term
 False
Definition
 Newton's first law applies to particles, rigid bodies as well as deformable bodies.
Term
 False
Definition
 Principle of transmissibility states that the conditions of equilibrium or of motion of a particle remain unchanged if a force acting on particle is replaced by another force of equal magnitude and opposite direction but same line of action.
Term
 True
Definition
 In many engineering problems the data is vary rarely known with an accuracy greater than 0.2 percent. Hence the answers to such problems must not be displayed with an accuracy greater than 0.2 percent.
Term
 True
Definition
 Vector operations described in chapter 2 are also called as vector algebra
Term
 False
Definition
 Rectangular components of a planar force are not necessarily in the same plane as the given force.
Term
 False
Definition
 Addition of two vectors is a non-commutative operation
Term
 True
Definition
 Triangle rule for vector addition results from two triangles forming a parallelogram which yield the same resultant
Term
 True
Definition
 The product of a scalar and any vector results in changing magnitude or direction or both magnitude and direction of that vector.
Term
 True
Definition
 A force can be resolved into unlimited number of components.
Term
 True
Definition
 When the lines of action of two components of a given force are known then it is possible to compute the magnitudes of both components of that force using the parallelogram law.
Term
 True
Definition
 Rectangular components of a force have their lines of action mutually perpendicular to each other
Term
 Commutative and Distributive
Definition
 The scalar product of vectors is
Term
 True
Definition
 The dot product of two vectors could be used to compute the projection of one vector along a given line.
Term
 True
Definition
 If the dot product of any two vectors is negative then the angle between those two vectors is more than 90 degrees.
Term
 True
Definition
 If two systems of forces are equivalent then they are also equipollent.
Term
 False
Definition
 A system of forces reduces to a WRENCH when the resultant force and the resultant moment due to all forces are perpendicular to each other.
Term
 True
Definition
 The magnitude of the moment of a force about a point is always more than that about a line passing thru that point.
Term
 True
Definition
 External forces are entirely responsible for external behavior of a rigid body
Term
 False
Definition
 Dot product is an operation on two vectors which results in the product of two scalars and the sine of the angle between the two vectors
Term
 True
Definition
 A clear decision should be made regarding the choice of the free body or bodies and separated from all other bodies.
Term
 to prevent translation or rotation or both of that rigid body
Definition
 The reactions at the supports, or connections or the joints of a rigid body are:
Term
 False
Definition
 For a two dimensional structure the equlibrium conditions yield four scalar equations
Term
 which has more unknowns than the number of equilibrium equations fomed from the principles in statics.
Definition
 A statically indeterminate structure is one
Term
 Commutative and Distributive
Definition
 The scalar product of vectors is
