Sound travels faster through rigid material like steel rather than through spongy materials like rubber. why?

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter
