Machine guards are barriers used to prevent the entry of any part of the human body into the moving equipment. Safety devices are controlling devices that stop or interrupt the machine’s operation when a part of the human body accidentally touches the machine. Write a short note on it various types of machine guard and sensors used in oil and gas industry (each 2.5 marks).

1: A square footing is to be constructed as shown in the Figure at a founding depth of 2 m. Using the Terzaghi equation compute the ultimate surface capacity, [ (qult)Surf ], possible for the layered soil profile shown. Keeping in mind that Terzaghi’s semi-empirical bearing capacity equation can only be applied to a soil layer with a thickness greater than or equal to the applied stress contact-area-breadth (either virtual or real breadth). In such a case, second layer cannot be assessed by the nominal equation of Terzaghi. An acceptable approach is to merge the second and third layers into a single layer with equivalent conservative properties. |

Assume that a two-lane small road crosses a two-lane main road at a right angle making a four-leg intersection where the traffic on the small road controlled by a yield sign. A shopping mall is located 108.24 ft from the centerline of the outside lane of the main road and 12 m from the centerline of the nearest lane of the minor road. Determine the maximum velocity (in km/h) that can be allowed on the small road if the speed limit on the main road is 39.77 mph. Grades of both the roads are leveled.
