What is the bank angle in a banked turn?
What is the bank angle in a banked turn?
- The angle at which the vehicle is inclined about its lateral axis with respect to the horizontal
- The angle at which the vehicle is inclined about its vertical axis with respect to the horizontal
- The angle at which the vehicle is inclined about its transverse axis with respect to the horizontal
- The angle at which the vehicle is inclined about its longitudinal axis with respect to the horizontal (correct)
What keeps a vehicle turning on a flat surface when the bank angle is zero?
What keeps a vehicle turning on a flat surface when the bank angle is zero?
- Inertia
- Centripetal force
- Gravity
- Friction or traction (correct)
What is the expression for the relationship between friction, mass, velocity, and radius in a banked turn?
What is the expression for the relationship between friction, mass, velocity, and radius in a banked turn?
- $rac{ ext{friction force}}{ ext{mass}} = rac{v^2}{r}$
- $rac{ ext{friction force}}{ ext{mass}} + rac{v^2}{r}$
- $rac{ ext{friction force}}{ ext{mass}} > rac{v^2}{r}$ (correct)
- $rac{ ext{friction force}}{ ext{mass}} < rac{v^2}{r}$
