How many binary joints are equivalent to one quaternary joint?

Solution:

Which of the following components is not part of a diesel engine?

Valve mechanism

Spark plug

Camshaft

Crankshaft

Solution:

The static deflection of a shaft under a flywheel is 4 mm. What is the critical speed in rad/s if g = 10 m/s²?

50 rad/s

20 rad/s

10 rad/s

30 rad/s

Solution:

How are the normal pitch (Pn) and axial pitch (Pc) related for a helical gear with helix angle α?

Pc = Pn * cos(α)

Pc = Pn / cos(α)

Pn = Pc * sin(α)

Pn = Pc / sin(α)

Solution:

The radius of the flywheel rim is 300 mm and the angular velocity is 30 rad/s. The tensile stress developed on it is (density is 1.6 kg/m³)

57.6 Pa

25.6 Pa

21.6 Pa

36.8 Pa

Solution:

coefficient of fluctuation of speed

maximum fluctuation of energy

fluctuation of energy

Solution:

Let a four bar mechanism is made up of links of length 200, 400, 600 and 700 mm.Now fix the longest link and tell the number of links that can still commit 360degree motion(crank motion) -

Solution:

In a Crank and Slotted Lever Mechanism, the angle subtended by the fixed link with the crank is 50 degrees. Calculate the ratio of Time of Cutting Stroke to Time of Return Stroke.

1.76

1.54

None of the above

2.6

Solution:

At which frequency ratio does the phase angle increase as the damping factor increases?

All of the above

When the frequency ratio is less than unity

When the frequency ratio is more than unity

Solution:

The torque delivered by a two-stroke engine is represented by T = 50000 + 600 sinθ + 800 cosθ. The mass of the disc-shaped flywheel is 400 kg with a diameter of 200 mm. Find the maximum angular acceleration of the flywheel. Round off to the nearest integer.
