Title of the Paper: Statics Date: 07.04.2022. Duration: 90 Minutes Max Marks: 50 Marks PART A ( 5 X 2 = 10 Marks) Answer All Questions 1. Define Forces. 2. Define Linear Momentum. 3. Define Earth Gravitation. 4. Define Tension 5. Define Hooks Law. PART B ( 5 X 2 = 10 Marks) Answer All Questions 6. The magnitude of the resultant forces of two given forces P,Q is R. If Q is doubled then R is doubled. If Q is reversed then also R is doubled. Show that P: Q: R = √2: √3: √2. 7. State the Laws of Friction PART C ( 3 X 10 = 30 Marks) Answer All Questions 8. Find the magnitude and direction of the resultant of F1 and F2 . 9. Two Forces of magnitude F1 and F2 act at a point. They are inclined at an angle α. If the forces are interchanged, show that their resultant is turned through the angle F F 2 tan 1 1 2 tan 2 F1 F2 10. The resultant of two forces of magnitude P and Q acting at a point, has magnitudes 2n 1 2 P2 Q2 and 2n 1 respectively. Show that tan 2 P2 Q2 when the forces are inclined at and 90o n 1 . n 1
