- (III) A curve of radius 78 m is banked for a design speed of 85km/h . If the coefficient of static friction is 0.30 (wet pavement), at what range of speeds can a car safely make the curve ? Hint:Consider the direction of the friction force when the car goes too slow or too fast.]
- Given the following three -dimensional stress state in matrix form determine the magnitudes of the principal stresses. If it is too lengthy , show the steps of how it can be calculated.

- Determine the magnitude of the electric field 14.8 cm directly above an isolated 3.68times 10^-5 C charge. Express your answer with the appropriate units. square
- Two charged objects separated by some distance attract each other If the charges on both objects are doubled with no change in distance between them. what happens to the magnitude of the force between the objects? The force between them remains unchanged The force between them is quartered The force between them also doubles The force between them quadruples The force between them is halved
- Two charged objects are separated by some distance The charge on the first object is greater than the charge on the second object. How does the force between the two objects compare? ) The second object exerts a large electrostatic force on the first object The charged objects exert electrostatic forces on each other that are equal in magnitude and pointing in the same direction. The charged objects exert electrostatic forces on each other that are equal in magnitude and opposite in direction The first object exerts a large electrostatic force on the second object
