The flywheel of a prototype car engine is under test. The angular position of the flywheel is given by x = (3.0rad/s3)t3 and the diameter of the flywheel is 36cm.
(a) Find the distance that a particle on the rim moves during that time interval.(b) Find the angle, in radians and in degree, at times t1 = 3.0s and t2 = 6.0s.(c) Find the average angular velocity, in rad/s and in rev/min, between t1 = 3s and t2 = 6s.(d) Find the instantaneous angular velocity at time t1 = 3.0s and t2 = 6.0s.
Given s=.30/(60-u), where s is the spacing (space headway) in miles, and u is the speed in miles per hour, derive the relationships u-k, u-q, and q-k. Also, estmate the capacity (qmax) of the roadway.
The center of gravity G of the 20-in. club is located 12 in. from the knob. knowing that at the instant, G has a velocity of 4 ft/s upwards and the club has an angular velocity of 30 rad/s counterclockwise
Determine the normal stress in a soccer ball if the internal pressure is 110 kPa, the outside diameter is 220mm and the wall thickness is 3mm .
the flow profile is such that u=u(max)*(1-(r/R)^2) where u is the flow speed and r is the distance from the centre of the pipe in the radial direction. What is the shear stress on the pipe wall What is the shear force exerted by the oil on a 1m lo..

a plane truss is subjected to a loads 2P and P at joints B and C, respectively, as shown in figure part a.The truss bars are made of two L102 x 76 x 6.4 stell angles having an ultimate stress tension equal to 390 MPa (cross-sectional are of the tw..
The coefficients of kinetic friction between the blocks and the inclined plane are a=0.1,b=0.3. Neglect the mass of the link. Angle between the inclined plane and the surface is 30 degree.
The concentration of trichloroethelyne (TCE) in an air sample near a hazardous waste landfill is 34 ppm, the ambient air temperature is 31 degrees C, and the atmospheric pressure is 0.94 atm. What is the TCE concentration in mg/m^3
The power loss, p , in a journal bearing depends on length, L; diameter, D; clearance, c; and rotational speed, w. You also have to worry about lubricant viscosity, density, and pressure. Obtain the dimensionless groups that charactrize this probl..
create a primary function that uses a function handle with a nested function to compute the ninimum of the function 20x^2-200x+12 over the range 0
The undeformed length of the spring is l. Knowing that the collar is released from rest at x = and neglecting friction between the collar and the horizontal rod, determine the magnitude of the velocity of the collar as it passes through point C.
If the initial concentration of parathion in the runoff from the agricultural field is 3 ppb, the velocity of the river is 2.3 miles/day, how many days will the fish hatchery have to contain river water in holding tanks until the parathion concent..
