A steel rivet 1.50 cm long and 1.5 mm radius has one end attached to a wall. If the other end is subjected to a shearing force of 6.0 × 104 N, what is the downward deflection? The shear modulus for steel is 8.27 × 1010 Pa.
A parachutist with a camera descends in free fall at a speed of 11 m/s. The parachutist releases the camera at an altitude of 100 m. How long does it take the camera to reach the ground
A railroad car with a mass of 25,000 kg rolls into a second stationary car with a mass of 50,000 kg. How fast was the first car moving before the collision
Determine the magnitude of the force between two point charges, Q1 = -2e located at (-3.60 cm, +4.10 cm) and Q2 = -8e located at (-0.60 cm, -8.60 cm). Continue working the problem above by calculating the direction of the force that Q1 exerts on Q..
