oyfr 3. The figure shows a frame under the influence of an external loading made up of five forces and two moments. Use the scalar method to calculate moments. a. Write the resultant force of the external loading in Cartesian vector form. b. Determine the & direction of the resultant moment of the external loading about A. 15 cm 18 cm 2.2 N-m B 50 N 45° 10 cm 48 N.m 250 N 60 N 20 21 50 N 25 cm 100 N A 118, 27cm 5, 4:1

Estimate the LFL and UFL for propylene using Equations 6-10 and 6-11 in the textbook,and compare these to the experimental values given in the table in Appendix B.

1. Determine the minimum compression ratio required to raise the temperature of air overhexane to its AIT. Assume an initial temperature of 20°C.2. Ethanol is kept in a storage vessel that is vented with air (at 25°C and 1 atm). Is theequilibrium mixture of vapor above the liquid and air flammable? What if the liquid isacetone instead?

2-7 The force P applied at joint D of the square frame causes the frame to sway and form the dashed rhombus. Determine the average normal strain developed in wire AC. Assume the three rods are rigid. I understand how you calculate length LAC its just the sqrt(400^2+400^2) = 565.685mm. I do understand that you have to take LAC'-LAC/LAC to get .0258mm/mm. I'm just not understanding the cosine law used to calculate LAC'. I guess what I'm asking is why do you use cos instead of sin or tangent? I've been trying to understand why that was used for a bit now and it's probably something simple I'm forgetting. If you can, please clarify it in detail. Thank you so much!

Assume the Link AO is the input and revolves 360°, determine a. the coordinates of limit positions of point B, b. the angles  (AOC) corresponding to the limit positions

A professor teaches two sections of a course: • 70% of students are in Section 1, and 30% are in Section 2. • In Section 1, 90% of students pass the final exam. • In Section 2, 80% of students pass the final exam. A student is randomly selected. a) Draw a tree diagram to represent this situation. b) What is the probability that the selected student passes the exam? c) Given that a student failed, what is the probability they were from Section 1?

.. A factory has two machines, A and B. Machine A produces 60% of the parts, while Machine B produces 40%. Machine A produces defective parts 5% of the time, while Machine B produces defective parts 10% of the time. A randomly selected part from production is inspected. a) Draw a tree diagram to represent the probability of getting a defective part. b) What is the probability that a randomly selected part is defective? c) If a part is found to be defective, what is the probability it came from Machine A?
