- Find the elongation of a rod made of aluminum and copper under a tension of 5.8×103 N. The dimensions of the rod are R=0.5 cm, LAl=10.5 m, LCu=5.5 m (Young moduli are 7.0×1010 Pa for Al and 11×1010 Pa for Cu)A person places his hand palm downward on a scale and pushes down on the scale until it reads (8.31x10^1) N. The triceps muscle is responsible for this arm extension force. Find the force (in N) exerted by the triceps muscle. The bottom of the triceps muscle is 2.50 cm to the left of the elbow joint, and the palm is pushing at approximately 35.0 cm to the right of the elbow joint. (please ignore the number 96 shown in the scale). Give your answer with three significant figures.4 2, Stress 1 Strain The point that identifies the fracture point of the material whose graph of stress as a function of strain is shown is O 3 O 2 O 4 O 5 O 1
- Kendra holds the end of a rope that is .5 kilograms and .60 meters long, while her friend Lupita holds it on the other end, with a force of 150 N. What is the torque that Kendra withstands? The rope has a Young's Modulus of 55x10^8 Pa, unfortunately, it cannot stretch more than 3 cmfrom 600 Newtons of tensile force, or else it would break apart. Would it break apart in this case?Before cutting a cable in a trench, how can a lineman be sure the correct cable has been isolated?Rubber has a Young's modiles of 1.5 x 10^8 Pa. If someone were to apply a force of 3 x 10^10 N to the side of a 12 m^3 cube, what would the strain on the cube of rubber be
