The area moment of inertia about the y-axis of a linearly tapered section shown in the figure is _____________ m4 .
(Answer in integer)
A cylindrical bar has a length πΏ = 5 π and cross section area π = 10 π2 . The bar is made of a linear elastic material with a density Ο = 2700 kg/m3 and Youngβs modulus E = 70 GPa. The bar is suspended as shown in the figure and is in a state of uniaxial tension due to its self-weight.
The elastic strain energy stored in the bar equals _________ J. (Rounded off to two decimal places)
Take the acceleration due to gravity as π = 9.8 m/s2.
A cylindrical transmission shaft of length 1.5 m and diameter 100 mm is made of a linear elastic material with a shear modulus of 80 GPa. While operating at 500 rpm, the angle of twist across its length is found to be 0.5 degrees.
The power transmitted by the shaft at this speed is _______kW. (Rounded off to two decimal places)
Take Ο = 3.14.
A cuboidal part has to be accurately positioned first, arresting six degrees of freedom and then clamped in a fixture, to be used for machining. Locating pins in the form of cylinders with hemi-spherical tips are to be placed on the fixture for positioning. Four different configurations of locating pins are proposed as shown. Which one of the options given is correct?
