mation mit All vers Left tion 1 Question 1. C Area A mplem tion 2 plete Ares AZ The figure (not drawn to scale) shows a prismatic bar subjected to axial (direct) forces F1 and F2. Given Young's modulus E=100 GPa, forces F=60 kN, F₂ = 90 kN, Lengths L₁ = 380 mm and L₂ = 200 mm, and cross-section areas A₁ = 190 mm² and A₂ = 500 mm², calculate the internal forces FBC and FAB in kN, the stresses σBC and σAB in MPa, and the total displacement dc in mm. Enter your answera in the boxes below. Respect the sign convention for tension and compression! The answers are acceptable within a tolerance of 1 kN for the force, 1 MPa for the stresses, and 0.01 mm for the displacement. FBC: kN FAB KN BC MPa AB: MPa δε : mm 16°C Mostly cloudy Q Search

Cycling The Campagnolo Hyperon Ultra Two carbon wheel, which has a diameter of 700 millimeters, has 22 spokes evenly distributed around the rim of the wheel. What is the length of the rim subtended by adjacent pairs of spokes (Figure 15)?

Tsunami Waves and BreakwatersThis is a continuation of Exercise 16. Breakwaters affect wave height by reducing energy. See Figure 5.30. If a tsunami wave of height H in a channel of width W encounters a breakwater that narrows the channel to a width w, then the height h of the wave beyond the breakwater is given by h=HR0.5, where R is the width ratio R=w/W. a. Suppose a wave of height 8 feet in a channel of width 5000feet encounters a breakwater that narrows the channel to 3000feet. What is the height of the wave beyond the breakwater? b. If a channel width is cut in half by a breakwater, what is the effect on wave height? 16. Height of Tsunami WavesWhen waves generated by tsunamis approach shore, the height of the waves generally increases. Understanding the factors that contribute to this increase can aid in controlling potential damage to areas at risk. Greens law tells how water depth affects the height of a tsunami wave. If a tsunami wave has height H at an ocean depth D, and the wave travels to a location with water depth d, then the new height h of the wave is given by h=HR0.25, where R is the water depth ratio given by R=D/d. a. Calculate the height of a tsunami wave in water 25feet deep if its height is 3feet at its point of origin in water 15,000feet deep. b. If water depth decreases by half, the depth ratio R is doubled. How is the height of the tsunami wave affected?

Solve these prism and cylinder exercises. Where necessary, round the answers to 2 decimal places unless otherwise specified. A solid right cylinder 9.55 centimeters high contains 1910 cubic centimeters of material. Compute the cross-sectional area of the cylinder.
