Need help on all questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.

Transcribed Image Text:A clamp holds a block as shown. If the weight of the block is W = 215 lb., and the coefficient of static
friction between the block and the clamp is, us(block) =0.36, what is the minimum amount of torque
required to keep the block from falling if the If the bolt with square threads, has a radius, r = 0.66 in., a

- Hi there sir/madam I'm not sure how to do this question could please help with this The bore diameter of each cylinder in a six-cylinder four-stroke petrol engine is 25 mm and the stroke length for each cylinder piston is 275 mm. During engine testing, the engine runs at 4250 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 7.85 cm2 and diagram length of 3.25 cm. For a pressure scale set at 525 kN/m2 per cm on the indicator diagram, calculate the indicated power developed by the engine. To 2 d.parrow_forwardready to move. Pick a mass of the object and one type of surface and record them. Mass (M) Surface type = kg, . Then click to start and keep observing force applied in lab quest. When object shows a kink means ready to move, check value of force, that is the force when it is equal to static friction force. It is the maximum value of force that appears in the screen and graph as maximum value of force. Record its value from graph.
