Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

Question

Please give me answer in 10 minutes I will rate

in a cam follower mechanism, running at
500 rpm, the follower is to be held against
the cam by a helical compression spring
with a force that varies between 80 and
160 lb as the spring length varies over a
range of 1.5 in. Springs ends are squared
and ground, and the wire material is to be
shot-peened Music wire, ASTM A228. The
outside diameter is 1.75 in. and the spring
index is 10. The spring is supported
between flat plates with fixed end. is this
spring safe for this application? justify your
answer by checking all possible modes of
failure and make comments with regard to
the safety of the spring.

Please answer the question in 5mins I will rate your answer. Cam mechanisms are used in many machines. For example, cams open and close the valves in your car engine to admit gasoline vapor to each cylinder and to allow the escape of exhaust. The principle is illustrated in the figure below, showing a follower rod (also called a pushrod) of mass m resting on a wedge of mass M. The sliding wedge duplicates the function of a rotating eccentric disk on a camshaft in your car. Assume that there is no friction between the wedge and the base, between the pushrod and the wedge, or between the rod and the guide through which it slides. When the wedge is pushed to the left by the force F, the rod moves upward and does something such as opening a valve. By varying the shape of the wedge, the motion of the follower rod could be made quite complex, but assume that the wedge makes a constant angle of ? = 19.0°. Suppose you want the wedge and the rod to start from rest and move with constant…

(3) A circular cam 8-in in diameter rotates off-center with an eccentrity e = 1" & operates the roller follower that is carried by the arm. The roller follower is held against the cam by means of a tension spring attached a third from a fixed pivot point. The force against the cam & roller follower is approximately 50lb @ the low position & 80lb @ high position. The ratio of the coil diameter to that of wire diameter is 7.0. The allowable stress on the spring is S,= 60,000psi. Calculate : P (a) the wire diameter; (b) the outside diameter of spring; (c) the number of active coils recommended.
