Engineering Mechanics Statics Exam
Questions With Complete Solutions
truss - Answerstructure composed of slender members joined together at their end
points
.two-force member - Answerthe force acting at each end of the member will be directed
along the axis of the member
.method of joints - Answerif an entire truss is in equilibrium, then each of its joints are in
equilibirum
.zero-force member - AnswerMembers that support no loading. Used to increase the
stability of the truss during construction.
.method of sections - Answerif an entire truss is in equilibrium, then any segment of the
truss is also in equilibrium
.multiforce member - Answermembers that are subjected to two of more forces
.frames - Answersupport loads
.machines - Answercontain moving parts and are designed to transmit and alter the
effect of forces
.shear force - Answerthe force component Vb that is tangent to the cross section
.normal force - Answerthe force component Nb that acts perpendicular to the cross
section
.bending moment - Answercouple moment Mb
.torsional moment - Answerapplied torque Mb in three dimensions
.shear force diagram - Answera graph of V versus x of the resulting function of x
.moment diagram - Answera graph of M versus x of the resulting function of x
.dry friction - Answeroccurs between contacting surfaces of bodies when there is no
lubricating fluid
.coefficient of static friction - Answerconstant of proportionality, "mu sub s" found by
dividing frictional force by normal force
