Question 1

Presence of moisture in a refrigerant affects the working

Question 2

A disc of 200mm diameter and 5 kg mass is mounted on the end of an arm of length 500mm. If the disc rotates about the arm at 300 rpm and other end of arm is free to rotate, find the speed of precession

Question 3

A steel bar(α= 11x10-6) is held by two fixed supports as shown in the figure and is subjected to an increase of temperature ∆T=100 °C and young's modulus 200GPa respectively, the magnitude of thermal stress (in MPa) induced in the bar is _____

Question 4

A cutting operation is performed with a rake angle of 10 and the friction angle of 52.if the cutting operation is assumed to be orthogonal having no built up edge formation and merchant circle analysis is valid. Find the cutting strain for such operation.

Question 5

Consider an elliptical shaped rail PQ in the vertical plane as shown. A block of mass 1 kg is pulled along the rail from P to Q with a force of 18 N which is always parallel to line PQ. The kinetic energy of the block in Joules, when it reaches Q will be

Question 6

Two disks A and B with identical mass (m) and radius (R) are initially at rest. They roll down from the top of identical inclined planes without slipping. Disk A has all of its mass concentrated at the rim, while Disk B has its mass uniformly distributed. At the bottom of the plane, the ratio of velocity of the center of disk A to the velocity of the center of disk B is.

Question 7

Water is coming out to the atmosphere from a converging channel with a velocity of 5 m/s as shown in the figure. At section A, a cylinder of 10 cm diameter containing a friction-less piston attached to a spring having spring constant 500 N/m is connected. The cross-section diameter of the channel at A and B is 2 m and 1 m respectively. Due to the flow the spring is compressed by an amount of

Question 8

A town with a population of 150000 people is supplied with water through a pipeline from a reservoir 100 km away. Water is consumed by the population at the rate of 130 litre/person/day. The supply is continuous. Considering only the friction loss, find the suitable size of the pipeline. The difference of levels between the reservoir water surface and center line of the pipeline at the town end is 45 m. Take friction factor: f = 0.04.

Question 9

A laminar fully developed fluid (k = 0.175 W/m-K) flow inside a 6 mm internal diameter tube under uniform wall temperature boundary conditions. Compute the heat transfer rate between the tube walls and the fluid for a length of 8 m if the mean temperature difference between the wall and the fluid is 50 °C.

Question 10

Annual demand of a product A is 4000 units. Cost of order is Rupees 900 per order. Handling charge per year is 10% of the unit price. Item can be purchased in lot as shown below.

The feasible EOQ should be

(ii)the value of is same for each demand
(iii) 
(iv)

Question 12

A Turbine is connected to the shaft by the rectangular key having width and thickness of 16mm and 10mm respectively. If the shaft has a diameter of 50mm the length of the key (in mm) is (shearing and crushing stress of a key material is 42 and 70MPa)

Question 13

A machine element has an ultimate strength , and endurance limit of . The fatigue curve for the element on log-log plot is shown below. If the element is to be designed for a finite of 10000 cycles, the maximum amplitude of a completely reversed operating stress is _________ .

Question 14

A cylindrical solid pipe of 500 mm3 volume is melted in a furnace. The melting point of the pipe material is 1200oC, the amount of heat required in kJ to melt the metal would be

Assume heat (J/mm3) needed to melt the metal varies by given expression

Question 15

The two shafts AB and BC, of equal length and diameters d and 2d, are made of the same material. They are joined at B through a shaft coupling, while the ends A and C are built-in (cantilevered). A twisting moment T is applied to the coupling. If TA and TC represent the twisting moments at the ends A and C, respectively, then
