What is the difference between longitudinal and circumferential stress?
Longitudinal stress is twice circumferential stress C. Circumferential stress is twice longitudinal stress Internal pressure can be produce by water, gases or others. When a thin – walled cylinder is subjected to internal pressure, three are two mutually stresses: Circumferential or Hoop stress.
What is meant by circumferential stress?
circumferential stress, or hoop stress, a normal stress in the tangential (azimuth) direction. axial stress, a normal stress parallel to the axis of cylindrical symmetry. radial stress, a normal stress in directions coplanar with but perpendicular to the symmetry axis.
What is longitudinal stress?
Longitudinal stress is defined as the stress produced when a pipe is subjected to internal pressure. The direction of the longitudinal stress in a pipe is parallel to the longitudinal axis of its centerline axis, which means that the stress acts in the direction of the pipe’s length.
Which stress is half the circumferential stress?
Explanation: Longitudinal stress is developed along the walls of the cylinder in the shell due to internal fluid pressure on the ends. The longitudinal stress is half the circumferential stress.
How do you get circumferential stress?
The circumferential stress, also known as tangential stress, in a tank or pipe can be determined by applying the concept of fluid pressure against curved surfaces. The wall of a tank or pipe carrying fluid under pressure is subjected to tensile forces across its longitudinal and transverse sections.
What is circumferential moment?
Circumferential moment = W/16 [ R^2 (3+u)-r^2 (1+3u)] At centre r=0 and Poisson’s ratio (u) = 0.2-0.25 for concrete which is very small. So, the moment becomes; M= W/16 [R^2 (3+0)], = 3WR^2/16.
How many types of longitudinal stress are there?
Ans: Tensile stress and compressive stress are the two types of longitudinal stress.
Are tensile stress and longitudinal stress same?
When a body is compressed under the action of applied forces, this restoring force per unit area is known as compressive stress. Tensile or compressive stress is also known as longitudinal stress.
What of the following is true about circumferential stress in thin cylinder 1?
Explanation: True, It is assumed that the stresses are uniformly distributed throughout the thickness of the wall. Explanation: The stress which is developed in the walls of the cylinder due to internal fluid pressure and which acts tangential to circumference is called hoop stress or circumferential stress.
What is the maximum circumferential stress when it is full of water?
Find the maximum height to which the tank may be filled if the circumferential stress is limited to 6000 psi. The specific weight of water is 62.4 lb/ft3….More Reviewers.

What is the relationship between longitudinal stress and circumferential stress?
B. Longitudinal stress is twice circumferential stress. C. Circumferential stress is twice longitudinal stress. D. There is no fixed relationship between the two. And the answer is…. C. Circumferential stress is twice longitudinal stress. Internal pressure can be produce by water, gases or others.
What is hoop stress and circumferential stress?
Circumferential or Hoop stress: This is the stress which is set up in resisting the bursting effect of the applied internal pressure and can be most conveniently treated by considering the equilibrium of the cylinder. The hoop stress is th Internal pressure can be produce by water, gases or others.
What is circumferential stress in a pipe?
Circumferential stress acts along the pipe’s circumference, with failure tending to split the pipe into two halves. The longitudinal stress in a pipe is smaller than the circumferential stress. The formula for circumferential stress demonstrates this. Figure 3: Parameters for Determining Circumferential Stress in a Cylinder ( source)
How do you calculate longitudinal stress in a closed cylinder?
For a cylinder closed closed in both ends the internal pressure creates a force along the axis of the cylinder. The longitudinal stress caused by this force can be calculated as. σ l = p d / (4 t) (2)
