- Question 4 i put D and it was incorrectarrow_forwardTRUE OR FALSE1. The primary and secondary suspensions are designed to achieve very poor ride quality, not safe performance during curve negotiation and bad dynamic behavior on a tangent track. 2. Each bogie frame is connected to car body through side bearings. 3. the wheel sets are located within a frame, either a bogie or directly in the vehicle, and are restrained by a large yaw stiffness. 4. When considering maintenance for railways, often the consequences can easily be changed. 5. Maintenance can only have positive effects. 6. Corrective maintenance also called as down systems. 7. the disadvantage of this system is the relatively low frequency of maintenance.arrow_forwardTechnician A says that leaf spring type suspensions are subject to wheel tramp.

The bumper should be released after each push and the vehicle should oscillate about 1½ cycles and then settle. Technician B says that one free upward bounce should stop the vertical chassis movement if the shock absorber or strut provides proper spring control. If the vehicle’s bumper does more than 1½ free upward bounces, the shock absorber or strut is defective. Who is correct?arrow_forward
