Unformatted text preview: Page 2 of 2 Problem 3. The large box on the right is on the verge of sliding downhill. Find the angle α . The friction forces are at maximum. Large box on the right: Weight = 200 lbs. μ s = 0.28 Small Box on the left: Weight = 100 lbs. μ s = 0.15 Problem 4. The cable supports a uniformly distributed load w = 600 N/m. Find T max and the angle of the cable at the connection points if the lowest point of the cable, h = 3 m . Hint: to find the angle of the cable take the derivative of the parabolic equation @ the end point. Problem 5. The mass of the cable per unit length is 2 kg/m. The allowable sag is 3 m. What is the: T max of Cable AB? Length of cable between Tower A and Tower B?...
