The crank of a slider crank mechanism is 15 cm and the connecting rod is 60 cm long. The crank makes 250 r. p.m in the clockwise direction. When it has turned an angle of 210 ϕ from the inner dead center (I. D.C) position, graphically determine:

a. Velocity of slider C

b. Angular velocity of connecting rod and

c. Linear velocity of the mid-point of the connecting rod (D).

d. Use complex number and instant center methods to check the results.

2. From the result of parts 1, graphically determine:

a. Acceleration of point C

b. Angular acceleration of connecting rod CB​

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.
