The roller and the rockers take over the elongations and the contractions of the joints part. And thus help in stabilising the structure. Thus when the bridges are extended over long routes a rocker or a roller is used at the joints.

Explanation:
When bridges are extended over long routes or distances, it is important to consider the effects of temperature changes on the structure. The expansion and contraction of the bridge due to temperature changes can cause stress and potential damage to the joints. To mitigate these effects, engineers often incorporate rockers or rollers at the joints.
Rockers and Rollers:
Rockers and rollers are types of bearings that allow for movement and rotation at the joints of a bridge. A rocker bearing is designed to allow rocking motion, while a roller bearing allows for rolling motion. Both types of bearings provide flexibility and accommodate the thermal expansion and contraction of the bridge.
Effects of Temperature:
When the temperature of the bridge increases, the materials expand. Conversely, when the temperature decreases, the materials contract. These thermal movements can lead to significant displacements and stresses at the joints of the bridge.
Benefits of Rockers and Rollers:
By incorporating rockers or rollers at the joints, the elongations and contractions of the joint parts are not significantly affected by temperature changes. This is because the rockers and rollers allow the bridge to move and adjust freely in response to temperature variations. The bearings effectively absorb the thermal movements, reducing the stress on the joints and preventing potential damage.
Flexibility and Safety:
Using rockers or rollers at the joints provides the bridge with the necessary flexibility to accommodate thermal expansion and contraction. This flexibility ensures the safety and integrity of the structure, as it minimizes the risk of excessive stress concentrations and potential failure.
Conclusion:
Therefore, the statement "When the bridges are extended over long routes or distance, a rocker or a roller is used at the joints. As when the temperature is raised, the elongations and the contractions of the joints part are not much affected if the rollers and rockers are used" is true. Rockers and rollers provide the necessary flexibility and allow for the smooth movement of the bridge, minimizing the impact of temperature changes on the joints.
