Learning Goal: To be able to find the center of gravity, the center of mass, and the centroid of a composite body. A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids. An object is made from a uniform piece of sheet metal. The object has dimensions of a = 1.25 ft, where a is the diameter of the semi-circle,b= 3.71 ft, and c = 2.30 ft. A hole with diameter d = 0.750 ft is centered at (1.09, 0.625).

Learning Goal: To determine an I-beam's maximum bending moment, moment of inertia using the parallel-axis theorem, and the maximum stress at a given location using the flexure formula. As shown, I-beam ABC supports a sign that weighs S = 30 lb . The I-beam is 24 in. long and is further supported by a rod that is attached 18 in. from the wall. Assume that all forces acting on the I-beam act along its centroid and that the I-beam's weight is negligible.

I Review Learning Goal: Part A - Drawing the free-body diagram of the pulley To draw the free-body diagram of a point particle, use the equations of equilibrium to find unknown forces, and understand how frictionless pulleys affect the transfer of force in a cable, The portion of the cable attached to the spring is at an angle of o = 35° from the ground. The spring has a spring constant of k=15.5 kN/m . The pulley is attached to the ceiling by rod BD that forms an angle 0 = 62.5° with the ceiling.Draw the free-body diagram of the pulley. Recall that the pulley is massless. As shown, a mass is suspended from a cable that wraps around a frictionless and massless pulley. The cable connects to a linear elastic spring. For this problem, treat the pulley as a point particle at B. Start all forces at point B in the center of the pulley. Draw all forces as tensile forces, or pulling forces. All angles should be measured from the positive x axis. They are positive in the counterclockwise…
An unknown object is suspended from a thin string and fully submerged in a container of water. Water surrounds the entire object as it hangs from the string, and the object is not touching the bottom of the water filled container. The object remains at rest at all times. The density of water is 1000 kg/m3. a) Draw a FBD using the unknown object as your system. Be sure to label the forces. b) The unknown object has an unknown mass M. The tension in the string is measured to be (3/5)M g. Calculate the density of the unknown object.

Learning Goal: To be able to solve three-dimensional equilibrium problems using the equations of equilibrium. Part A As with two-dimensional problems, a free-body diagram is the first step in solving three-dimensional equilibrium problems. For the free-body diagram, it is important to identify the appropriate reaction forces and couple moments that act in three dimensions. At a support, a force arises when translation of the attached member is restricted and a couple moment arises when rotation is prevented.For a rigid body to be in equilibrium when subjected to a force system, both the resultant force and the resultant couple moment acting on the body must be zero. These two conditions are expressed as The J-shaped member shown in the figure(Figure 1) is supported by a cable DE and a single journal bearing with a square shaft at A. Determine the reaction forces Ay and Az at support A required to keep the system in equilibrium. The cylinder has a weight WB = 6.00 lb , and F = 1.40 lb…

Learning Goal: To calculate the maximum allowable stresses in pressure vessels, compute the minimum allowable thickness of pressure vessels to meet certain constraints, and observe and compare properties of different pressure vessel shapes. Engineers are considering two possible vessel shapes for storing fuel. One shape is cylindrical and the other is spherical. Each vessel would be constructed out of the same material such that its hoop stresses and longitudinal stresses would be no greater than 120 MPa. The cylindrical pressure vessel has an inside diameter of de = 800 mm and a thickness of te = 25.0 mm. The spherical pressure vessel has an inside diameter of ds = 650 mm and a thickness of t = 11.0 mm. ▼ Part A - Maximum allowable pressure in the cylindrical pressure vessel Determine the maximum allowable pressure, pc,max, in the cylindrical pressure vessel.
