Power Transmission System-Assessment

1. What is the primary source of power for operating an EOT crane?

• Diesel engine 

• Hydraulic system 

• Electric motors 

• Pneumatic System

What does the term "cross travel" refer to in the context of an EOT crane?

• Lifting heavy loads vertically

• Moving the crane along the tracks

• Moving the load horizontally across the bridge

• Controlling the hoist speed

In a power transmission system, what is the function of a gearbox?

• To convert electrical energy to mechanical energy

• To regulate voltage levels

• To change the speed and torque of the output

• To store excess power

What is the role of a belt drive in a mechanical power transmission system?

• To change the speed and torque of the output

• To transfer power between shafts

• To convert electrical energy to mechanical energy

• To store energy

Which type of gear is used to change the direction of rotation in a mechanical system?

• Spur gear

• Worm gear

• Bevel gear

• Helical gear

In a mechanical system, what is the function of a universal joint coupler?

• To allow for angular misalignment between shafts

• To provide high torque transmission

• To convert electrical energy into mechanical energy

• To store energy

In a bevel gear system, what is the angle between the intersecting shafts?

• 45 degrees

• 60 degrees

• 90 degrees

• 120 degrees

What is the voltage in a circuit if a current of 2 amperes flows through a resistance of 4 ohms?

• 2 volts

• 4 volts

• 6 volts

• 8 volts

What is the difference between a spur gear and a helical gear?
