question 36

Multiple Choice

A 1000-kg barge is being towed by means of two horizontal cables.One cable is pulling with a force of 80.0 N in a direction 30.0° west of north.In what direction should the second cable pull so that the barge will accelerate northward,if the force exerted by the cable is 120 N? Assume that the water exerts no appreciable frictional drag on the barge.

• A)19.5° east of north
• B)21.1° east of north
• C)39.0° east of north

Definitions:

Motor Load Current

The current drawn by an electric motor under specific load conditions, indicative of the power it is using to perform its function.

Inverse Time-Delay

Refers to a characteristic of protective devices where the time to trip decreases as the magnitude of the current increases.

Overload Current

The flow of electricity exceeding the normal operating current, potentially causing overheating or damage to electrical components.

Overload Units

Devices or mechanisms designed to protect electrical circuits and motors from operating above their rated capacity, preventing damage.
