An object weighing 10 grams is spinning in a centrifuge such that an acceleration of 13.0 g is imposed to it. the arm connecting the shaft to the object is r = 6.0 inches. if a = acceleration = rω2 where ω = angular speed in rad/s, determine:
mass of the object in lbm
rpm (revolutions per minute) of the shaft
force acting on the object in lbf

1) 0.022 lbm

2) 276.253 RPM

3) 0.287 lbf

Explanation:

Given data:

mass = 10 kg

acceleration -

7.53 m/s^2

r =6 inches = 0.1524 m

1) mass in lbm  

as 1 kg = 2.2 lbm

2) acceleration

SO IN

3) Force in

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
