Read and Analyze the sample problems given. Give a thorough analysis stating what type of situation the author dealt, how the problem was solved, the assumptions that the author considered in solving the problem, and why where these assumptions made. Sample Problem 7.2The 100-lb block in Fig. (a) is at rest on a rough horizontal plane before the force Pis applied. Determine the magnitude of P that would cause impending sliding tothe right.W = 100 lbSolution4, = 0.5HE = 0.2The problem statement clearly specifies that sliding impends. Because we knowwhere it impends (there is only one friction surface), we conclude that this is aType II problem.The free-body diagram of the block is shown in Fig. (b), where the frictionforce is shown acting to the left, opposite the direction of impending sliding. Thereare three unknowns in this FBD: P, N, and F. There are also three independentequations: two equilibrium equations and Coulomb's law for impending sliding.From the FBD we see that the equilibrium equations give N = 100 lb andP = F. Coulomb's law then yields(a)100 lbP = F = Fmax = M,N = 0.5(100) = 50 lbAnswerFINThis completes the solution. Because there were no assumptions, no checks are(b)necessary.CommentNote that Fig. (a) in both Sample Problems 7.1 and 7.2 is identical. The differ-ences are revealed only in the problem statements. This shows that you must readeach problem statement very carefully, because it determines the problem type.A problem statement can imply impending sliding. For example, the followingare equivalent to the original statement of this problem: They both imply that Pisto be calculated for impending sliding.1. Determine the largest force P that can be applied without causing the block toslide to the right.2. Determine the smallest force P that will cause the block to slide to the right.

In the given questions we need to find the magnitude of P which will be caused due to slidding .…

A forensic engineer accepts a retainer from an attorney for a plaintiff and receives selected documentation from the attorney. Subsequently the engineer bills for work that includes a review of the case documentation. Still later, because of a disagreement with the attorney, the engineer ceases to perform the work without delivering a report to the attorney and all of the documentation provided earlier. Several months later, the engineer is approached by the defense attorney's in the same case and accepts an assignment to function as an expert for the defense in the same legal dispute. Was it ethical for the engineer to accept the new assignment? OA. Yes. Several months passed before she was approached by the defense attorneys. O B. No. She did not have the consent of all concerned parties. OC. Yes. She returned all moneys paid her. O D. No. She drew no conclusions during her firs review of the material.
