Aux 1 Unit 9 Q1

1 / 10

Why are spherical bearings used at the ends of the rams in a two-ram steering gear system?

C) To reduce the speed of the ram movement

D) To eliminate the need for lubrication

B) To accommodate angular misalignment and pivoting motion as the rams move

A) To allow for precise linear movement only

2 / 10

Which component is typically used to allow the rams to pivot while exerting force on the tiller in a two-ram steering gear?

C) Linear bearings

A) Fixed bushings

B) Spherical bearings

D) Rotary encoders

3 / 10

What is the function of the tiller in the two-ram steering gear system?

D) To control the flow of hydraulic fluid to the rams

B) To transfer the linear force from the rams to the rudder stock to rotate the rudder

A) To convert rotational motion into linear motion

C) To maintain the alignment of the rams

4 / 10

What fitting is necessary to secure the connection between the ram ends and the tiller in a two-ram steering gear system?

D) Hydraulic clamps

B) Bolted flanges

C) Pin joints with spherical bearings

A) Welded joints

5 / 10

What is the role of the hydraulic power unit (HPU) in the operation of a two-ram steering gear?

A) It filters the hydraulic fluid

C) It aligns the rams with the tiller

D) It provides electrical power to the system

B) It controls the direction and speed of the rams by supplying pressurized hydraulic fluid

6 / 10

In what way do spherical bearings improve the safety of a two-ram steering gear system?

B) By ensuring that the rams can move freely without causing misalignment or stress on the tiller, reducing the risk of mechanical failure

D) By preventing the rams from extending

C) By decreasing the hydraulic pressure

A) By increasing the system’s speed

7 / 10

How do spherical bearings contribute to the longevity of a two-ram steering gear system?

D) By preventing the rams from moving

A) By increasing the operating pressure

C) By eliminating the need for hydraulic fluid

B) By reducing friction and wear at the connection points between the rams and the tiller

8 / 10

Why is it important for the rams to be synchronized in a two-ram steering gear system?

A) To prevent the rudder from rotating

C) To increase the speed of the rudder movement

B) To ensure that the tiller is moved evenly and the rudder is steered accurately

D) To allow the rams to operate independently

9 / 10

In a typical two-ram steering gear arrangement, where are the rams positioned relative to the tiller?

A) Parallel to each other and connected on opposite sides of the tiller

B) Perpendicular to each other and connected to the center of the tiller

C) Diagonally positioned, with one ram above the tiller and one below

D) One ram is positioned vertically, and the other horizontally

10 / 10

What could happen if spherical bearings were not used in the ram ends of a steering gear system?

A) The rams would operate more efficiently.

D) The hydraulic pressure would increase.

C) The steering system would become more responsive.

B) The system could experience increased wear, misalignment, and potential failure due to the inability to accommodate angular movement.
