# ASSIGNMENT NO 1 Last Date of Submission- 3 Jan 2025 ## Questions 1. Explain various types of force system 2. State and explain Newton's first law, Newton's second law, Newton's third law and Newtons Law of gravitation. 3. Determine magnitude and directional sense of resultant moment of the forces about point P. - A diagram of point P is shown, with forces and distances labelled. - Force 400 N applied at 30 degrees. - Force 260 N applied at 13/12 degrees. - All forces are applied vertically. - Point O is at the origin. - Point B is 2 meters to the right of point P. - Point P is 3 meters to the right of point O. 4. State and explain Varignons theorem. 5. Calculate the moment of 250N force on the handle about centre of the bolt. - Diagram of a wrench with handle. - Distance between centre of bolt and point of force application 300 mm. - Distance between centre of bolt and centre of handle 200 mm. - Force is applied 15 degrees clockwise from the horizontal. 6. If the resultant moment about point A is 4800 NM clockwise, Determine the magnitude of F3, if F1=300N and F2=400N. - Diagram of a beam. - Point A is at the origin. - Force F1 is 30 degrees clockwise from the horizontal and 2 meters from point A. - Force F2 is 60 degrees clockwise from the horizontal and 3 meters from point A. - Force F3 is perpendicular to the beam and 4 meters from point A. 7. Determine resultant R of two forces 400 N and 600 N. - Diagram of a nail with two vertical forces applied - Force 400 N applied downwards. - Force 600 N applied upwards.
