Force exerted by the tool on the chip acting normally to the tool face 2. Horizontal cutting force exerted by the tool on the workpiece 3. Frictional resistance of the tool against the chip flow acting along the tool face 4. Vertical force which helps in holding the tool in position Select the correct answer using the codes given below.
In metal machining, the zone where the heat is generated due to friction between the moving chip and the tool face is called
Which of the following sequence of Heat zones is/are correctly placed? A) Torrid zone, South temperate zone and Frigid zone. B) Torrid zone, North temperate zone and Frigid zone. C) South temperate zone, torrid zone and Frigid zone. Select the correct answer given below.
6 faces of a cube is painted with different colour. Red face is opposite to the black face. The face adjacent to the bottom face is white. Brown face is adjacent to blue face. Red face is at the bottom. Which face will be on exactly opposite to the brown face.
Which of the following is NOT true about Frictional force? A. Friction is the force which opposes the relative motion of two surfaces in contact. B. The force of friction that acts when a body is moving (sliding) on a surface is called sliding friction. C. Friction in machines wastes energy and also causes wear and tear. D. Rolling friction is much more than sliding friction, the use of ball bearings in a machine considerably reduces friction.
While discussing about friction, a teacher gave a number of examples to explain the concept. Some of the examples where friction is useful in our day-to-day life as quoted by the teacher are given below : A. We are able to write because of friction between the tip of the pen and the paper. B. We are able to walk because of friction between our feet and the ground. C. A ball thrown vertically upwards comes back to us due to friction. D. We are able to stop a moving vehicle by applying brakes because of friction. The correct examples were
A, B, C, D, E and F are six girls who use 6 different face wash – Pond’s, Lakme, Lotus, Garnier, Himalaya and Kaya (but not necessarily in the same order). They also like six different colours – Red, Blue, Brown, Peach, Black and White (also not necessarily in the same order. A and C do not like a Red colour.
