A horizontal aluminum rod 3.2 cm in diameter projects 3.8 cm from a wall. A 1300 kg object is suspended from the end of the rod. The shear modulus of aluminum is 3.0-1010 N/m2. Neglecting the rod's mass, find (a) the shear stress on the rod and (b) the vertical deflection of the end of the rod. (a) Number i Units (b) Number i UnitsThe figure shows the stress-strain curve for a material. The scale of the stress axis is set by s = 300, in units of 10 N/m2. What are (a) the Young's modulus and (b) the approximate yield strength for this material? Assume & = 0.0090. Stress (106 N/m?) 0 0 E Strain (a) Number i Units (b) Number i UnitsAfter a fall. a 77 kg rock climber nds himself dangling from the end of a rope that had been 19 m long and 8.5 mm in diameter but has stretched by 2.4 cm. For the rope, calculate (a) the strain. {b} the stress. and {c} the Young's modulus. (a) Number n Units v (b) Number n Units v (c) Number n Units v A water pipe having a 2.90 cm inside diameter carries water into the basement of a house at a speed of 0.887 m/s and a pressure of 173 kPa. If the pipe tapers to 1.29 cm and rises to the second floor 6.40 m above the input point, what are the (a) speed and (b) water pressure at the second floor? (a) Number i Units (b) Number Units vAbout 32% of the body of a person floating in the Dead Sea will be above the water line. Assuming that the human body density is 0.943 g/cm , find the density of the water in the Dead Sea. Number i Units
