The uniform crate shown below has a mass of 20 kg. If a force P = 80 N is applied to the crate, determine if it remains in equilibrium. The coefficient of static friction is µ̟ = 0.3.

Describe the steelmaking process to obtain a cold thin coil, in SAE 1008 steel, MSG 20 (thickness 0.91 mm) plate with a width of 600 mm starting from a hot-rolled plate. MSG 8 (thickness 4.25 mm) with a width of 1200 mm Requirements: LE min = 300 MPa, LR between 400 and 500 MPa and A min = 20%. The sheet must have a good surface finish and dimensional control. Ensure high Tenacity. Cite and justify the necessary process. Cite the hardening mechanisms used

Problem#3: You need to design a metallic glass for use in industry. The glass transition temperature of the metallic glass is 250°C. While in use, the sample will be subjected to a permanent tensile stress for tuse=6 years and at a temperature of Tuse=230°C. You need to do the necessary creep experiment in the lab to predict the performance of this material by applying the same stress at different temperature and different time. The creep test will be carried out for tiab=6 hours. At what temperature, Tlab, can this test be performed in the lab under the same tensile stress? [Hint: Use WLF and VFT equations for two cases: 1) Tref=Tg =250 °C and 2) Tr=260 °C.]

Determine the single uniformly distributed load in the x direction that would produce the same deformation in the y direction as the original loading for a given rectangular block with the following data: 4 inches long in the x direction, 2.5 inches long in the y direction, and 3.5 inches long in the z direction. The block is subjected to a triaxial loading of three uniformly distributed forces as follows: 52 kips tension in the x direction, 68 kips compression in the y direction, and 49 kips tension in the z direction. Given v = 0.28 and E = 30 x 10° psi, O a. 265.23 kips O b. 255.80 kips Oc 220.25 kips O d. 246.56 kips

Q1: How do your results for μs and μk compare to literature values for dry metal on plastic? Cite what you compared to. Do they agree with the literature within error? If not, discuss any systematics that could have contributed to the discrepancy. Q2:  Is the force of static friction constant as the incline rises? Explain your answer. My Us value is 0.4452, and Uk value is 0.33
