Transcribed Image Text:Q5 (a) A circular cylindrical steel tank contains a volatile fuel under pressure as shown in
Figure Q5(a). A strain gage at point A records the longitudinal strain in the tank
and transmits this information to a control room. The ultimate shear stress in the
wall of the tank is 84 MPa, and a factor of safety of 2.5 is required. Determine the
value of the strain should the operators take action to reduce the pressure in the
tank?
(Data for the steel are as follows: modulus of elasticity E= 205 GPa and Poisson's
ratio v=0.30.)

I will rate you with “DOWNVOTE/DISLIKE”, if you don’t answer every question. THANK YOU.arrow_forwardTwo lenses are shown in the following figures. The one shown in figure 1 is thinner from the edges and thicker in the middle (centre) while the lens shown in figure 2 is thicker from the edges and thinner in the middle (centre). ALPHALAS GmbH is a German laser manufacturer. As a high-tech laser company, they are offering a wide range of products in the fields of lasers, optics, and laser-related electronics. You have been hired by the said company and as your first assignment you have to repair a laser machine. During the inspection you found out that a lens in missing in that machine due to which the machine is unable to diverge the laser beam. The purpose of the missing lens is to diverge the laser beam. Now you have only two lenses and you have to select one lens among the two (provided in the figures below) for the said job. Which lens will you select and why? Explain your answer with suitable explanation. Also explain how your recommended lens will diverge the laser beam. Draw the…arrow_forward
- Please answer the given question and show the solution. Thank you very much! Note: Please include the units in the solution and use 4 decimals point in Final Answer.arrow_forwardi need this quickly please please please because I study for my homework it is in mechanical engineering:dynamicarrow_forward! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. At an intersection car B was traveling south and car A was traveling 30° north of east when they slammed into each other. Upon investigation, it was found that after the crash, the two cars got stuck and skidded off at an angle of 10° north of east. Each driver claimed that he was going at the speed limit of 50 km/h and that he tried to slow down, but couldn't avoid the crash because the other driver was going a lot faster. The masses of cars A and B were 1500 kg and 1200 kg, respectively. 10° 30° VR Determine the speed of the faster of the two cars if the slower car was traveling at the speed limit. The speed of the faster car was km/h.arrow_forward
