Thermoset polymers exhibit the following primary

type of bonding.

• covalent

• ionic

• saturated

• van der Waals

Orthographic drawings

• may contain 3D sketches.

• must always be dimensioned.

• can only be created using drawing instruments.

• consist of multiple two-dimensional drawings.

Welding as a joining process is

• permanent.

• semi-permanent.

• temporary

• all of the above

The velocity ratio of a pulley system is

• equal to the mechanical advantage.

• the efficiency of the system.

• the same as the number of pulleys.

• found by counting the number of ropes supporting

  the lower block.

Identify the correct statement about second-class

levers.

• The load arm moves further than the effort arm.

• The effort arm moves further than the load arm.

• The system operates at a mechanical disadvantage.

• The fulcrum is positioned between the effort and

  the load.
