Two steel wines support a moveable overhead camera weighing W = 28 lb (see figure part a) used For close-up to viewing of field action at sporting, events. At some instant, wire I is at an angle a = 22° to the horizontal and wire 2 is at angle fi = 40°. Wires I and 2 have diameters of 30and 35 mils, respectively. (Wire diameters are often expressed in mils; one mil equals 0.001 in.) (a) Determine the tensile stresses s and s 2 in the two wires. (b) If the stresses in wires 1 and 2 must be the same, what is the required diameter of wire 1 ? (c) To stabilize the camera for windy outdoor conditions, a third wire is added (see figure part b). Assume the three wires meet at a common point coordinates (0, 0. 0) above the camera at the instant shown in figure part b. Wire I is attached to a support at coordinates (75 ft, 48 ft, 70 Ft). Wire 2 is supported at (-70 ft. 55 ft, 80 Ft). Wire 3 is supported at (-10 ft. -85 Ft, 75 ft). Assume that all three wires have a diameter of 30 mils. Find the tensile stresses in all three wires

The figure shows a bicycle wheel resting against a small step whose height is h = 0.100 m. The weight and
radius of the wheel are W = 20.0 N and r = 0.390 m. A horizontal force is applied to the axle of the wheel. As
the magnitude of increases, there comes a time when the wheel just begins to rise up and loses contact
with the ground. What is the magnitude of the force when this happens?

The shaded shape is supported by Cable 1 and Cable 2 in the position shown (Drawing is NOT to
scale). The shape has a uniform weight per unit area of 11kN/m2.
Step 1: If A=1.9m, C=0.4m, x=1.2m, y=1.7m, z=3.5m, a = 67°, and B = 18°, find the value of B

needed to keep the shape in static equilibrium. Then solve for the tension in Cable 1 (T1) and the
tension in Cable 2 (T2).
Once you have evaluated your values for B, T1 and T2 it is recommended that you redraw your free
body diagram with the correct dimensions, weights, and forces T1x, T1y, T2x, T2y and confirm that
you do have your problem correctly in horizontal, vertical, and moment equilibrium.
Step 2: Once you have confirmed that you free body diagram is in equilibrium, solve the following
equation: Z= T1+T2
Write your final answer for Z (in kN) in the answer box below. Round your answer to two decimal
places.
