Question 4: Two moments of equal magnitude are applied to the following circular cross-section, as shown in the figure. The area of overall tension and overall compression are colored green and red, respectively. Which of the following figures is accurate? Note: please reach out to me if you can't decipher the colors in these figures. CT CT] 45° [<] lo Nam lo Nam [<] lo Nm lO Nm (a) (b) [T) lo Nam lo Nm CT] lo Nm 1O Nm (d) (c)

Please help. This problem involves moments of inertia on a circular cross-section. Thank you.

Given the vector in the figure above has a magnitude of 23.8 [N], what is the z-component of the vector? (Note: the black dashed line in the figure is the projection of the vector onto the x-z plane). The use of significant digits is not required. Report your answer to the hundredths-place. Do not include units in your answer; units are taken as [N]. Z y O 47.3° 25.10 X

Given below are the (x,y,z) coordinates of four points. (The units are feet) Point A: [16, 38, 12] Point B: [37, 0, 30] Point C: [0, 30, 24] Point D: [32, 0, 0] A force (vector) F, is applied at point C. its line of action passes through point A and the direction of the force is towards point A (from point C). The magnitude of the force is 150lbs. 1. Determine the (x, y, z) components of the force F. That is, express F in Cartesian component form. 2. Determine the position vector īc/D (which defines the location of point C relative to point D. That is, find the vector DC. 3. Compute the vector M,C, which is the moment applied at point D due to the force Fc. 4. Compute the vector ÁDB, which is the unit vector which points from point D towards point B. 5. Compute M, which is the moment applied about the line (i.e. axis) DB due to the force F. (The result here is a scalar) 6. What are the angles (0x, Oy, 0z) that the components of the unit vector ADA (pointing from point D towards point…
