QUESTION 1 Spring is an elastic body whose function is to store energy when deflected by force and return equivalent amount of energy on being released. For the purpose of saving energy and improving the performance of vibration isolation system, advanced springs with light weight effect and high performance have been widely used for today's automobiles and mechanical systems. A helical spring is a reliable elastic component usually used in the suspension of automobile to absorb shocks caused due to irregularities of the road surface and to provide a comfortable ride to passengers. A static music wire helical compression spring is needed to support a 90 N load after being compressed 50 mm. The solid height of the spring cannot exceed 35 mm. The free length must not exceed 95 mm. The static factor of safety must be calculated and the value must be equal or exceed 1.15. For the robust linearity, use a fractional overturn to closure of 0.15. The spring must operate in a 30 mm diameter hole. A 1.2 mm diametric clearance allowance should be adequate to avoid interference between the spring and the hole due to swelling of the spring diameter as the spring is compressed and out of round coile The

As illustrated in the figure below, the bedplate of an experimental diesel engine is supported on four springs to isolate the vibrations from the test frame. The effective weight of the diesel engine and bedplate is 43kg and the stiffness of each of the four springs is 250 kN/m. Using a simplified approach - by applying Newton's Second Law assuming a single degree of freedom system and ignoring damping - what rotational engine speed is best avoided?
