The rigid bar AC is supported by a pin at F and two identical links BD and CE. The length between point A and B is 22 in, between B and F is 3 in, and between F and C is 4 in. The length of the links are 9 inches. Both are made of brass (E = 15 * 10^6 psi) and have a cross sectional area of .25 sq. in. The pin used at support F has a diameter of 1/2 in and is under single shear. Determine the largest load P that can be applied at point A knowing that the normal stress magnitude in each link is not to exceed 24 ksi, the shearing stress in pin F is not to exceed 15 ksi, and the deflection of point A is not to exceed .08 in.
Describe on your own words the three strengthen mechanism for metals (i.e. grain size reduction, solid solution strengthening and strain hardening). Be sure to explain how dislocations are involved in each of the strengthening techniques.
What tightening torque should be used if the connection is permanent and the fasteners are lubricated? What portion of the external load is taken by the bolts? By the members?
Determine the radius of the crank R and the speed n of a slider crank mechanism, used in a shaker table. It is required that the average speed of the table is 5 m/s, and the maximum absolute acceleration is 3000m/s^2. Assume ratio R/L=0.2
The explanation provided below, provide the solution to the problem in simple and easy to understand steps. A turbofan engine on a test stand in the maintenance shop is being run at a continuous setting of 22,700 lbs of thrust. The TSFC is 0.5 lbs/..

Determine distribution of shear force and bending moment
In the idealized model attached shown, m = 15 kg, k = 135 N/m, and the viscous damping ratio is 0.15. Assume that an external harmonic force F(t) = 15 cos 4 t acts on the system with F0=15 N and forcing frequency of 4 rad/s.
Determine the natural frequencies of the system. For the baseline system I get natural frequencies at the following engine speeds: 435, 2026, 2818, 5225, 7093, 10245, and 12153 rpm.
