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 = 1.05 ft , where a is the diameter of the semi-circle,b = 3.74 ft , and c = 2.45 ft . A hole with diameter d = 0.700 ft is centered at (0.925,0.525) . Part A Find the area of the body. (Figure 1) Express your answer numerically in feet squared to three significant figures. Part B Find x¯ , the x -coordinate of the body's centroid.

(Figure 1) Express your answer numerically in feet to three significant figures.
This exercise is part of a series of problems aimed at modeling a situation by progressively refining our model to take into account more and more parameters. This progressive approach is very close to whatwhat do professional scientists do! contextWe want to lower a suspended load in a controlled way, so that it hits the ground with a speed whose modulus is not too great. To slow down the descent, we added a resort behind the mass (A), Lasuspended load (B) is connected by a rope passing through a pulley to another mass (A), which slides on a horizontal surface with friction.InformationThe masses of loads A and B are known.The mass of the rope itself is negligible (very small compared to the loads).The pulley has negligible mass and can rotate without friction.Load B is initially stationary and is at a known height h.The surface on which mass A is placed is horizontal.There is friction under mass A: the kinetic friction coefficient u, is known.The rope attached to mass A is perfectly…

A student team is to design a human-powered submarine for a design competition. The overall length of the prototype submarine is 95 (m), and its student designers hope that it can travel fully submerged through water at 0.440 m/s. The water is freshwater (a lake) at T = 15°C. The design team builds a one-fifth scale model to test in their university’s wind tunnel. A shield surrounds the drag balance strut so that the aerodynamic drag of the strut itself does not influence the measured drag. The air in the wind tunnel is at 25°C and at one standard atmosphere pressure. At what air speed do they need to run the wind tunnel in order to achievesimilarity?
Data has been gathered from a lifting system used to remove spent RBMK fuel rods from the spent rod pool into long term safe storage. At present the spent rods are winched up from the pool and then lowered into concrete barrels in a second pool. When it is positioned properly the winch is released and the rod is allowed to drop in. The following calculation is based on data gathered from the present set up. Time taken to lowered into concrete barrels = 10 Seconds Winch drum diameter = 0.9m Mass of load = 185 kg Initial velocity = 0 m/s Distance travelled = 6m You have been asked to use this information to determine: The final linear velocity of the load The linear acceleration of the load The final angular velocity of the drum The angular acceleration of the drum The tension force in the cable The torque applied to the drum In determining the above quantities, you should clearly state the formulae used and apply dimensional analysis techniques to show that all values/units used…
Please solve this question. Subject: Transportation engineering Problem No.2 Fillet Radius Problem (Airport Engineering) Determine the minimum lead-in and the radius of the fillet to maintain the cockpit over the centerline for an aircraft with a 200.4 ft wingspan (i.e. airplane design group V), a wheelbase of 90.5 ft, undercarriage width of 41.3 ft, and the distance between the main undercarriage and cockpit equal to 95.3 ft. The aircraft is moving between two parallel taxiways through a connecting taxiway which has a centerline perpendicular to the parallel taxiway. (Assume taxiway width is 75 ft, the minimum safety margin is 15 ft, centerline radius is 150 ft).
