Asingle strain gage, placed in the vertical plane on the outer surface and at an angle of 60° to the axis of the pipe, gives a reading at point a of pa = -250(10-6 ). determine the vertical force p if the pipe has an outer diameter of 1 in and an inner diameter of 0.6 in. the pipe is made of c86100 bronze.

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
