ISRO 2010 Mechanical Engineering Questions, Answers and Explanation

50. In simple harmonic motion the acceleration is proportional to
a) Displacement
b) Linear Velocity
c) Angular Velocity
d) Rate of change of angular velocity

Answer
a) Displacement

In simple harmonic motion (SHM), some physical quantity varies sinusoidally. 
Example, simple harmonic motion is a spring object system on a friction-less surface. The object is attached to one end of a spring. The other end of the spring is attached to a wall at the left. the spring force depends on the distance x , the acceleration is not constant.It is a second order linear differential equation, in which the second derivative of the dependent variable is proportional to the negative of the dependent variable.

The Da Vinci Code trip

Chapter I of the novel begins with Robert Langdon asleep in the Ritz Hotel. Our trip begins with ourselves just outside the Ritz Hotel. One of the posh hotels with a lot of high end luxury cars parked outside. Ritz Hotel, Paris Sitting up now, Langdon frowned at his bedside Guest Relations Handbook, whose cover boasted:     SLEEP LIKE A BABY IN THE CITY OF LIGHTS. SLUMBER AT THE PARIS RITZ. In the beginning on his way to Louvre - The crisp April air whipped through the open window of the Citroën ZX as it skimmed south past the Opera House and crossed Place Vendôme . As the Citroën accelerated southward across the city, the illuminated profile of the Eiffel Tower appeared, shooting skyward in the distance to the right. Symbologists often remarked that France—a country renowned for machismo, womanizing, and diminutive insecure leaders like Napoleon and Pepin the Short—could not have chosen a more apt national emblem than a thous...

ISRO 2017 December Mechanical Questions, Answers and Explanation

ISRO 2017 December Mechanical Questions, Answers and Explanation Question Set E 1. The specific metal cutting energy is expressed as a)  τ cos(β - α) ⁄ sin φ cos(φ+β-α) b)  τ sin(β - α) ⁄ sin φ cos(φ-β+α) c)  τ cos(α - β) ⁄ sin φ cos(φ-β+α) d)  τ sin(α - β) ⁄ sin φ cos(φ+β-α) where  α is rake angle,   β is friction angle,  φ is shear angle and    τ is the shear stress. Answer a)    τ cos(β - α) ⁄ sin φ cos(φ+β-α) Explanation [ Manufacturing Technology ] Specific metal cutting energy is defined as the energy expended in removing a unit volume of work-piece material.  = Energy/Volume Removed Energy = Force of cut x velocity of tool Volume Removed = Velocity of tool x Width of cut x Depth of cut Specific metal cutting energy = Force of cut/(Width of cut x Depth of cut) Shear force = shear stress x Area of shear  =  τ  x width of cut x depth of cut /sin  φ Shear force/Force of cut ...
