A
High strength
High stiffness
Low mass
Low cost
2
Q
what are the five types of loading?
A
Pure torque Concentrated force Uniformly distributed load Triangular distributed load Trapezoidal distributed load
3
Q
What are the types of beam support?
A
Simply supported beam
Cantilever- supported at one end
Fixed-fixed end support- built-in supports at both ends
Fixed- simple supported
4
Q
What is a bending moment?
A
A moment caused in a structural element when an external force or moment is applied to the element causing the element to bent
5
Q
What is the equation for bending stiffness of a beam?
A
Bending moment/deformation
Bending moment=MR
6
Q
What is the bending moment equal too?
A
Youngs modulus*moment of area
