If P is the point in any plane of the tringle ABC show that the forces PA, PB, PC are equal to 3PG, where G is the centriod of the tringle.
ABCD is a quadrilateral. Forces is represent by BC, BA, DC, DA are acting at a point . show that the resultant will be represented by four times the line joining the mid points of the diagonal.
ABCD is a Quadriletral and E is the point of intersection of the lie of joining the middle point of the oppsite sides . Prove that the resultant of the forces represented by OA ,OB, OC, OD, is given by 4OE wherever the point O may be . when will these forces be in equalibrium.
If P,Q,R,S be the middle point the side of a quadilatral ABCD and O is any point , show that the forces represented by OA, OB, OC, OD have same resultant as the forces represented by OP, OQ, OR, OS.
ABCD is a parallelogram and P is any point in its plane . A particle P is attracted towards A and C by forces proportional to PA and PC respect. and repel from B and D by forces proportional to BP and DP respectvely. show that P is in equalibrium in all positions.
Show that the resultant of the forces OA tanA and OB tanB acting along the sides OA and OB of a tringle OAB is AB. tanB.tanA and act in the direction of the perpendicular from O on AB.
O is a point in the plane of tringle ABc. AO meets BC in D Show that component along AB and AC respectively of the forces represented by AD are
1) 1/2 AB and 1/2 Ac if O is te centriod.
2) \(b\over(b+c) \) AB and \(c\over(b+c)\) AC if O is the incentre.
3) \(tanB\over(tanB+tanC)\)AB and \(tanC\over(tanB+tanC)\) AC if O is the orhogonal of the triangle.
