In a single cylinder, four stroke, single acting gas engine, the cylinder diameter is 180 mm and the stroke is 350 mm . When running at 250 rpm , the mean area of the indicator diagram taken off the engine is 355 mm² , length of diagram 75 mm , scale of the indicator spring 90 kN/m sq per mm , and the number of explosions was counted to be 114 per minute. Calculate the indicated power.
so i have already asked this question and got a good answer, however on step 4, i dont understand how they reached 18.43 KW. When i do the math provided, i get the answer 7195.566. Where am i going wrong? thanks
StepsTo clarify how we determined the Indicated Power, I'll go over each step in detail.
Step 1: Comprehending the Provided Information - Cylinder diameter (in meters) = 180 mm = 0.18 m - Stroke length (in meters) = 350 mm = 0.35 m - Engine speed = 250 rpm -Indicator diagram mean area = 355 mm²
The diagram's length is 75 mm; its spring scale is 90 kN/m² per mm, or 90,000 N/m² per mm; and…

- An acrobat is walking on a tightrope of length L =20.1 m attached to supports A and B at a distance of 20.0 m apart. The combined weight of the acrobat and his balancing pole is 900 N, and the friction between his shoes and the rope is large enough to prevent him from slipping. Neglecting the weight of the rope and any elastic deformation, determine the deflection (y) and the tension in portion AC and BC of the rope for values of x from 0.5 m to 10 m using 0.5 m increments. 1. Determine the maximum deflection (y) in the rope. 2. Plot tension of AC and BC vs. x (on the same plot with x on the x-axis). Turn in the plot and the table of x, TAC, and TBC (clearly label each).
