A vertical shaft with the diameter of 28mm carries two belt pulleys. The shaft carries an axial compressive load of 6.2kN. The...

Can you give the free body diagram sketch..
If your problem is only to incorporating the 6.2kN axial compressive load into the equation, you can added it to the bending...

If b (2,-2) is the image of a(4,2), under axial symmetry in the line M, find the equation of M.

Thanks!

 Point A = (x,y) = (4,2)
 Point B = (x,y) = (2,-2)

The equation of line AB is:

  y = mx + b

 (-2) = m(2) + b        equation 1

   (2) = m(4) + b        equation

1. The preferred conformation of cis-3-tert-butyl-1-methylcyclohexane is the one in which:
A. the tert-butyl group is axial and the methyl group is equatorial.
B. the methyl group is axial and the tert-butyl group is equatorial.
