railway RRB JE (CBT I + CBT II) Mock Test 2024 Engineering Mechanics Kinematics and Kinetics Curvilinear Motion
Three identical cars A, B, and C are moving at the same speed on three bridges. Car A moves on a plane bridge, B on a convex bridge, and C on a concave bridge. FA, FB, and FC are the normal forces extorted by the cars on the bridges, then we can say that
1
FC is maximum
2
FB is maximum
3
FA is maximum
4
\(F_A = {F_B} = {F_C}\)
