A charge per unit length given by λ(x) = bx, where b = 12 nC/m2, is distributed along the
x axis from x = +9.0 cm to x = +16 cm. If the electric potential at infinity is taken to be
zero, what is the electric potential at a point P on the y axis at y = 12 cm?

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
