During a high Reynolds numberexperiment, the total drag force acting on aspherical body of diameter \{D=\) 7 cmsubjected to airflow at 1 atm and 5°C ismeasured to be 5 N. The pressure dragacting on the body is calculated byintegrating the pressure distribution(measured by the use of pressure sensorsthroughout the surface) to be 2.1 N.Determine the friction drag coefficient ofthe sphere.For the same values as above, find thevelocity of air during the test. Given thatdensity and viscosity of air at 50C5oC are1.269kg/m3 and 1.754×10-5kg/ms.

There are some assumptions as follows: (1) steady and…

C9-103 The band wrench of Fig. P9-103 is used to un- screw an oil filter from a car. (The filter acts as if it were a wheel with a resisting torque of 40 lb - ft.) The coefficient of friction between the band and the filter is 4, = 0.15, and the friction between the end of the wrench and the filter may be neglected. Plot P, the minimum force that must be applied to the wrench to loosen the filter, as a function of a (1 in. s as 5 in.). 5.5 in. -55 in.- 10 in. 40 Ib-ft

1) Calculations for the red dog food can rolling down the slope in the Rube Goldberg design are as follows (we will name it Step 1): Step 1 (calculations are given): Coefficient of friction → μ = 0.14 Mass of the object-m-368 gm = 0.368kg Initial height of the object (red can on top of books) → h=8.89, cm = 0.0889 m Slope of the file folder → 9 = 14° Travelling Distance by the object = 11.5 inch = 0.292 m And length that the object will travel=h/sin 0 = 0.0889/ sin14° = 0.367 m So, the radius of the object →R=0.367 -0.292 = 0.075 m Initial Velocity of red can → u=0 Velocity and Force Calculations for Step 1: -From total mechanical energy conservation: → Initial mechanical energy = final mechanical energy → mg - In case of pure rolling, the velocity of the center of mass: →V=Ro= 0.075 x 14.28 = 1.07 m/s. -Hence the change in force acting on the object for the travel: →F=mgsin0 = 0.368 × 9.81 × sin14° =0.89 N Step 2: The Selective Step (Step 2) in this design and for the questions below…
