Center of Gravity and Centroid

The term center of gravity indicates the position or location of a point about which the whole weight of a body or system is supposed to be concentrated, which means the whole weight of the body or system works through this point. It is closely related to mass distribution. For all positions of the body, the center of gravity would be a single point.

A centroid is an object's geometric center. For an object of
uniform composition, its centroid is also its center of mass.
Often the centroid of a complex composite body is found by,
first, cutting the body into regular shaped segments, and then
by calculating the weighted average of the segments'
centroids. An object is made from a uniform piece of sheet
metal. The object has dimensions of a = 1.45 ft, where a is
the diameter of the semi-circle, b = 3.22 ft, and c = 2.05 ft. A
hole with diameter d = 0.650 ft is centered at (1.15, 0.725).
Part E
The specific weight of the cone and scoop of ice cream are Ycone = 10.0 lb/ft³ and Yice cream = 45.0 lb/ft³, respectively. What is, the location
of the center of gravity of the cone (i.e., the cone and scoop of ice cream)?
Express your answer numerically in feet to three significant figures.

Diogram height, cm 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. Give your answer in kilowatts (kW) to 2 decimal places.

Tire manufacturers recommend that you check your tire pressure monthly to avoid unnecessary tire wear and enhance safety. This is best done when the tires are cold meaning; the car has not been driven for at least 2 hours. Since you leave for work before the sun comes up you decide to inflate your tires to the recommended pressure right after you get home from work in the afternoon when the tires are still warm. What would you find if you rechecked your tire pressure after the tires have cooled down? A.Tire pressure has decreased because there is a decrease in kinetic energy of themolecules resulting in more collisions with the inside walls of the tire thusincreasing the pressure inside the tire. B.Tire pressure has increased because there is a decrease in kinetic energy of the molecules resulting in fewer collisions with the inside walls of the tire thus decreasing the pressure inside the tire. C.Tire pressure has increased because there is an increase in kinetic energy of the…
