Situation 3. Determine the I, and Iş of the object below if the dimension of a = 12in , b = 7in. The radius of the semicircle is R= 20in and the radius of the hollow circle is 1.5in. Note: the hollow shapes are located in the center y 15 in 3 in

The force of an L-shaped round bar is shown in the figure below. Assuming that bending moment, torque and shear force effects need to be considered, try to calculate the vertical displacement of point C. E of the entire section is 200 GPa, G is 75 GPa, I, J The calculation with A assumes that the radius of the rod is 30 mm.

3) The T shaped cross-section of a beam is made of a flange (the upper horizontal area A1 = 2000 mm2) and a web (the lower vertical area A2 = 3200 mm?) as shown in the figure. 20 mm If you want to compute the vertical distance C, of the centroid of this cross-section from the bottom most point of this cross- а. section then give the expression in terms of some numbers from which Cy can be computed. No need to carry out the calculation. b. From part (a) if you get Cy = 114.6 mm then give the final expression of the area moment of inertia Ix (about the x-axis going through the centroid of the T-section). Your expression should only contain some numbers. No need to finish the calculation. Give the final expression of the area moment of inertia ly (about the y-axis going through the centroid). Your expression should only contain some numbers. No need to finish the calculation. d. If you drill a circular hole of 15 mm diameter with its center 160 mm С. 20 mm 100 mm coinciding with the…

The question is in the picture. Thanks

Rigid bar ABC is supported by two aluminum alloy (E = 10,000 ksi) rods as shown below. The horizontal distance between rods (1) and (2) is a = 120 in. Rod (1) has a length of L1 = 87 in. and a cross-sectional area of A1 = 0.65 in.2.  Rod (2) has a length of L2 = 84 in. and a cross-sectional area of A2 = 1.15 in.2. Rigid bar ABC is to remain horizontal under a load of P = 25 kips. Determine the distance x (in inches rounded to the nearest tenths) from joint A to the location of load P so that bar ABC remains horizontal.

Identify the equation for the deflection at point C.
