Question 13 Object "m" is suspended by a string (string 1) connected to the ceiling. String 2 connects "m1" to another object "m2" below it. Each object has a mass of 20kg.
a. Sketch the objects showing the masses and strings.
b. Draw the Free Body Diagram for each mass, and label each force.
c. Are either (or both) masses in equilibrium? Why?
d. What is the tension in string 2 Show your work.
What is the tension in string 1 Show your work.
f. Which tension is greater and why?

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
