Calculate and plot the radial and circumferential stress distribution in the left ventricle at the end of systole (P-80mmHg, assume that the ventricle is a spherical shell). The inner radius of the heart is 3.2cm and the outer radius of the heart is 3.8cm. The external pressure surrounding the heart is negative 1mmHg. Under a disease condition where the heart muscle thickens, calculate the radial and circumferential stress distribution in the left ventricle at the end of systole and at peak systole. Under these conditions the pressure remains the same but the inner wall radius is 3cm and the outer wall radius is 4.2cm. Compare this to normal conditions and comment. 2.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
