Which of the following tests uses a heavy pendulum for the breaking of a specimen while inspection? Correct Answer Charpy v-notch test

In the Charpy v-notch test, the specimen is first heated to a specified temperature. Then it is placed in a machine and broken within five seconds. This testing machine uses a heavy pendulum to break the specimen. This test indirectly provides fracture toughness of the material or casting.

A pendulum clock is lifted to a height where the gravitational acceleration has a certain value of g. Another pendulum clock of same length, but of double the mass of the bob is lifted to another height where the gravitational acceleration is $$\frac{g}{2}$$. The time period of the second pendulum would be (in terms of period T of the first pendulum)

A rock specimen of 120 mm length and 54 mm diameter is subjected to uniaxial compressive loading. Two strain gauges, one axially and other radially, are attached to the specimen. At the breaking load, if these two gauges read 0.0082 m/m and 0.0023 m/m respectively, the Poisson's ratio of the specimen is

Directions : Following question consists of a statement followed by three arguments I, II and III . You have to decide which of the arguments is a STRONG arguments and which is a WEAK Argument. Statement : Should admission to all professional courses be made on the basis of past academic performance rather than through entrance tests? Arguments : I. Yes. It will be beneficial for those candidates who are unable to bear the expenses of entrance tests. II. Yes. Many deserving candidates securing high marks in their qualifying academic examinations do not perform well on such entrance tests. III. No. The standard of examinations and assessment conducted by different Boards and universities are not comparable and hence there is a need to conduct entrance tests to calibrate them on a common yardstick.
