Example 1. A horizontal platform rests on four vertical springs, each of stiffness 15 kN/m. What will be the frequency of oscillation of the table if it has a mass of 2 kg? Determine also the angular frequency and the periodic time. (27.6 hz, 173 rad/s, .036 s )

Expert Solution

In this numerical,a platform is supported on 4 springs.So in this case all the 4 springs will deflect equally and hence they are in parallel arrangement.So we will first find equivalent stiffness and then using the respective formulas, required answers can be evaluated.

I have written the page number for your reference.

If you like my answer then please give me a " Thumbs Up ".It motivates me to solve more questions and help more number of students.

A vertical close coiled helical spring must have a stiffness of 4,3 kN/m. The maximum shear stress of 130 MPa is induced by a load of 720 N. With the spring fully compressed, the vertical height over the coils is 250 mm. If G = 79 GPa, calculate: 3.1 the required wire diameter for the spring; 3.2 the mean coil diameter and the number of coils.
