Chapter 3, Problem 41P

Q1: A. One of the researchers discovered a patent related to the development of a certain software module in mobile devices, and when he emailed one of the companies producing these devices, they asked him to send the research to try it on their devices, and after a while this researcher discovered that his discovery was used by this company without referring to him or buying this discovery, What do you think about the above. B. As a quality control engineer in one of the electrical appliance factories, I discovered that the technical worker responsible for inspecting one of these products seals its validity without inspecting it. when I filed a complaint with the administration, the administration neglected the complaint, arguing that there was no time to inspect it again due to lack of time to prepare the consumer. 1. What are the consequences of this action, it is possible that there is a bad in the product due to lack of examination. 2. The actions that you should take because of…

The pump shown in figure delivers water from the lower to the upper reservoir at arate of 2 cfs. The energy loss between suction inlet and the pump is 6 lbf-ft/lbf and betweenthe pump outlet and the upper reservoir is 12 lbf-ft/lbf . Both pipes are 6-inch schedule 40steel pipe. Calculate (a) the total head on the pump and (b) the power delivered by the pumpto the water

4. Now consider the figure below showing a wooden block subjected to biaxial loading, and its stress state in the laboratory coordinate system. The grain in the wood is aligned at an angle of 15° to the vertical direction as shown. Determine the stress state in the orientation of the grain. Y σy = 1.8 MPa 15° σx = 3 MPa ох ==
