Question

Use the equations derived to compute pulling force for the CLIP process to generate graphs of force, F, versus radius, R (up to 50mm radius), for power law indices of n=1, 0.8, 0.6, 0.4 and 0.2. For the consistency index, m, use 1 Pa-s. For the dead zone thickness use 50μm and 100μm (50μm results in higher resolution). Use vertical printing speeds of 100mm/hour and 300mm/hour n+3) 2n+ Please present your results in two graphs of F versus R: one for 100mm/hour and another for 300mm/hour, respectively Please comment on the various effects: Shear thinning behavior, dead-zone thickness, part size and printing speed.

Answer 1

We know that the For a black hole of mass m is, - L_Edd = 4 pi mG m_px/a_T where, - M = mass of the black hole G = Gravitational constant = 6.67 times 10^-8 CGS unit. M_p = Portion of mass/energy of the particles emerge as radiation c = velocity of light = 3 times 10^10 cm/sec a_T = Thompson cross section = 4.71 times 10^-55 cm^2 \r\n Therefore L_Edd = 4 pi times m times 6.67 times 10^-8 times 0.1 m times 3 times 10610/4.71 times 10^-55 erg/s = 4 pi times 1.416 times 10^47 times 3 times 10^10 times 0.1 m time sM [In this m_p = 0.1 m] = 53.387 times 10^56 mm erg/s = 53.357 times 10^56 m erg/s [for gas we take m = 1] = 53.387 times 10^56 times m/(3 times 10^10)^2 times 1/(3 times 10^10)^2 c^2/s = 53.387/9 times 9 times 10^56 times 10^-40 mc^2/s
