The variables of the equation are: F which represents force, k which is called the spring constant and measures how stiff and strong the spring is, and x is the distance the spring is stretched or compressed away from its equilibrium or rest position.
F = –kx. Boundary Conditions The Stiffness Method – Spring Example 1 Consider the equations we developed for the two-spring system. Refer the picture below for deflection formulas. Please note that SOME of these calculators use the section modulus of the geometry cross section ("z") of the beam. stiffness matrix, we must apply some form of constraints or supports or the structure will be free to move as a rigid body. The Westergaard method of rigid pavement analysis assumes that the concrete pavement is founded on a dense liquid foundation. the minus sign shows that this force is in the opposite direction of the force that’s stretching or compressing the spring. Stiffness and Bending Young's Modulus | Moments of Inertia | Bending Configurations | Evaluation Tools Introduction One very common problem that students have in 2.007 is not making their arm or structures stiff enough. Spring Stiffness Calculator . A lack of stiffness is very common cause of machine unreliability.
For an elastic solid foundation the following equation can be used to calculate the radius of relative stiffness with the same parameters but with E s equal to the Young’s modulus of the subgrade and v s equal to the Poisson’s ratio of the subgrade. It is a measure of the extent to which the string withhold to resists deformation in response to the applied force. As you might imagine, some shapes will perform better in some load cases than others, and some parts will need to be bigger to accommodate higher loads. A more flexible object would have less stiffness and vice versa. Remember from … And, the deflection for a simply supported beam would be different for different kinds of loading. It's stiffness, K, or spring constant if you will, per Hooke's Law F=kx, is F=kx k = F/x k = F/(FL^3/3EI) k = 3EI/L^3 which is the inverse of the deflection under a unit load. We will consider node 1 to be fixed u1= 0. A feature’s shape and size impact the formulas required to calculate stiffness, so we’ll consider those geometric properties first. Spring stiffness refers to the force that is required to cause the unit deflection. Stiffness (K) can be calculated by using the formula Force/deflection (N/m). The term stiffness refers to the rigidity of an object. Structural Beam Deflection, Stress Formula and Calculator: The follow web pages contain engineering design calculators that will determine the amount of deflection and stress a beam of known cross section geometry will deflect under the specified load and distribution. It is expressed as the ratio of load to deflection and depends on the bearing type, design and size. Bearing stiffness The stiffness of a rolling bearing is characterized by the magnitude of the elastic deformation (deflection) in the bearing under load. You are asking why, I think, you use the cantilever stiffness for a fixed pinned column in a frame with a load applied at the joint. This is a problem because the arms and structures usually need to move or support things.
