Question

It is common to mount machines and rotating equipment on shock isolation pads to reduce the transmission of time varying forces to the ground. In the system shown in the figure below, a machine represented as a mass m, has vibrational force acting at its center of mass in addition to the gravitational force. The pad that supports the machine is made of a damping material with nonlinear stiffness given by the constitutive equation F = cx^2, where c = 25 N/m^2. The material also has damping properties that are approximately linear, that is, the damping force is proportional to the velocity across the pad. a) Draw the system graph. b) Write the elemental equations c) Write the node equations d) Write the compatibility equations e) Identity the state variables and sources

Explanation / Answer

73 - Electron is negatively charged particle so when an atom loses the electron its become positively charged.

SO the answer is option C.

74 - erythropoietin is a hormone which is help in the production of red blood cells. This hormone activates the signaling for red blood cells production in the bone marrow. This hormone is synthesized in the kidney.

SO the correct option is option D - is a product of the kidney

75 -

Rh factor plays an important role during the pregnancy. If the foetus is Rh-positive and mother is Rh-negative then this will leads to the formation of the antibody which will cause the death of the foetus.

Option A is correct - RhoGam is used to prevent sensitization of the mother.

76 -

The correct option is option A - is an intercalated disc

77 - Statum basale is also known as stratum germinativum

So the answer is Option A
