bearing and shear
bending and shear
bearing and bending
bearing, shear and bending
Answer is Right!
Answer is Wrong!
The correct answer is: D. bearing, shear and bending
The pin of a rocker bearing in a bridge is designed to withstand the following forces:
- Bearing force: This is the force that is applied perpendicular to the surface of the pin. It is caused by the weight of the bridge deck and the traffic that is crossing the bridge.
- Shear force: This is the force that is applied parallel to the surface of the pin. It is caused by the bending of the bridge deck.
- Bending force: This is the force that causes the bridge deck to deform. It is caused by the weight of the bridge deck and the traffic that is crossing the bridge.
The pin of a rocker bearing in a bridge is typically made of steel. It is a cylindrical rod that is inserted into a hole in the rocker arm. The rocker arm is a steel plate that is attached to the bridge deck. The pin is held in place by a nut that is tightened on the other end of the pin.
The pin of a rocker bearing in a bridge is a critical component of the bridge. It must be able to withstand the forces that are applied to it without failing. If the pin fails, the bridge could collapse.
Here is a brief explanation of each option:
- Option A: Bearing and shear. This option is incorrect because the pin of a rocker bearing in a bridge is designed to withstand bending force as well as bearing and shear force.
- Option B: Bending and shear. This option is incorrect because the pin of a rocker bearing in a bridge is designed to withstand bearing force as well as bending and shear force.
- Option C: Bearing and bending. This option is incorrect because the pin of a rocker bearing in a bridge is designed to withstand bearing, shear, and bending force.
- Option D: Bearing, shear and bending. This option is correct because the pin of a rocker bearing in a bridge is designed to withstand bearing, shear, and bending force.
