Problem 8.6 2 of 10 Review Each piston has a radius of 45 mm and the cylinder has a wall thickness of 2 mm . Force P acts on plungers moving toward each other in a cylinder of radius 45 millimeters. Part A Determine the maximum force P that can be exerted on each of the two pistons so that the circumferential stress in the cylinder does not exceed 8 MPa . Express your answer to three significant figures and include appropriate units.

P = 4.5 x 10³ N = 4.5 KN

Explanation:

The circumferential stress will be the stress acting upon the circumference thickness area of the cylinder due to the force P. It can be calculated by following formula:

Cs = P/2πrt

where,

Cs = Circumferential Stress = 8 MPa = 8 x 10⁶ Pa

P = Force = ?

r = radius of cylinder = 45 mm = 0.045 m

t = thickness of cylinder wall = 2 mm = 0.002 m

Therefore,

8 x 10⁶ Pa = P/(2)(π)(0.045 m)(0.002 m)

(8 x 10⁶ Pa)(5.65 x 10⁻⁴ m²) = P

P = 4.5 x 10³ N = 4.5 KN

the answer is 46 mls because when you add the speed per second it increses the speed

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
