The connection points of members of a truss.

A surface or shape exposed by making a straight cut through something at right angles to the axis.

A support that prevents translation and rotation in a beam.

A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.

A diagram used to isolate a body from its environment, showing all external forces acting upon it.

A plate or bracket for strengthening an angle in framework.

The absolute value of a number

Slender straight pieces of a truss connected by joints.

The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.

A mathematical property of a cross section (measured in inches4) that determines the relative stiffness of an object related to its shape.

A support that prevents translation in any direction.

The resultant of a system of force is the vector sum of all forces.

A support that only prevents a beam from translating in one direction.

A physical quantity that has magnitude only.

A truss composed of triangles, which will retain its shape even when removed from supports.

A quantity that has both a magnitude and direction
