does plywood follow hooke's law? is the young's modulus for plywood constant across the beam? :) and if u have any other hints with deam deflection I am willing to have them :P
thanks!
thanks!
Hooke's law is a principle in physics that states the force needed to extend or compress a spring by some distance is proportional to that distance.
Hooke's law can be applied to plywood in the same way it applies to other materials, as long as the plywood is experiencing elastic deformation (meaning it can return to its original shape). This means that the force required to bend or deform the plywood is directly proportional to the amount of bending or deformation.
No, plywood may not always follow Hooke's law due to factors such as the type and quality of the wood used, the direction and magnitude of the force applied, and the thickness and number of layers of the plywood. However, for small deformations, plywood typically follows Hooke's law.
Hooke's law can be used to calculate the stiffness of plywood by plotting the relationship between the force applied and the resulting deformation, and then calculating the slope of the resulting line. This slope represents the stiffness or spring constant of the plywood.
Yes, for small deformations, plywood has a linear relationship between stress and strain, meaning that the amount of stress (force per unit area) applied is directly proportional to the amount of strain (change in length per original length) experienced. This is in accordance with Hooke's law.
