2 cards from this section. Quick, good the night before a test.
What is the formula for calculating the area of the +r plane?
Consider the dimensional aspects of the cylindrical element.
Define traction in the context of structural mechanics.
Think about how pressure might exert forces on a surface.
What is assumed about the traction on both the +r and −r planes?
Consider why simplifications are made in models.
True or False: The area of the +r plane is derived from height multiplied by the curved edge.
Visualize how areas are computed.
Consider a cylindrical pipe with an inner radius of 0.5 m and a wall thickness of 0.02 m. If the internal pressure exerts a traction of 150 N/m², calculate the total force exerted on the inner wall of the pipe.
Calculate the inner radius and use it in the area formula.
A cylindrical vessel has a height of 2 m and a radius of 1 m. If the internal pressure creates a constant traction of 100 N/m², determine the net outward force on the curved surface area only.
Curved surface area calculation can be broken down into height times circumference.
