Exam 11: Designing Structural Systems

A structural subcomponent using the triangle shape is rarely used in structural design because of its inherent instability.

A ____ is a structural member which projects beyond its support and is supported at only one end.

____ forces try to pull the element apart such as the force on the rope in a tug-of-war.

Beams are primarily designed to resist ____ forces.

____ form(s)the basis for classical Newtonian mechanics.

A(n)____________________ factor determines how much a product,or an element within a product,is overbuilt.

____________________ (also known as torque)is most associated with mechanical systems,such as motors,engines,and the related moving parts.

When a calculation is to include the weight of the material making up the structure,as well as loads that may be distributed over the entire surface,a(n)____ load (UDL)measure is used.

In applications such as an automobile drive shaft or simply spinning on a single rope swing seat,the structural element is under torsion.

What is a vector?

____________________ are lines that describe both the direction and magnitude of a force being applied to the system.

Bow's notation is a method of identifying forces within a structure.

If the breaking point of a jack is 6,000 pounds,and the maximum expected load is 4,000 pounds,what is the safety factor?

A(n)____________________ is a body that supports a load and resists external forces without changing its shape,except for that due to the elasticity of the material(s)used in construction.

_____ loads include the weight of all occupants in the building as well as things that can be moved,such as furniture

The stage after the elastic stage is known as the ____ stage.

If a 10-inch block changes in length by 0.5 inches,what is the strain?

____ is the conscious decision on the part of the designer to produce a product that will become outdated in a defined time frame.

Modern ____________________ bridge designs are capable of spanning the greatest distance of all bridge designs.

Dynamic loads are characterized by forces at rest.
