Three Forces P Q R Are Acting At A Point In A Plane Three forces P, Q, R are acting at a point in a plane The angle between P, Q and Q, R are 150° and 1° respectively, then for equilibrium;. If we call the first part p and the second part q then we know that p results in q This means that if p is true then q will also be true This is called the law of detachment and is noted $$\left (p \to q)\wedge p \right \to q$$ The law of syllogism tells us that if p → q and q → r then p → r is also true This is noted. Transposition (p → q) ∴ (¬q → ¬p) if p then q is equiv to if not q then not p Material Implication (p → q) ∴ (¬p∨q) if p then q is equiv to not p or q Exportation ((p∧q) → r) ∴ (p → (q → r)) from (if p and q are true then r is true) we can prove (if q is true then r.

13 The resultant of the two forces P and Q is R If Q is doubled, the new resultant is perpendicular to P Then 1 Q = R 2 None of these 3 Q = 2R 4 P = Q 14 The forces, which meet at one point and their lines of action also lie on the same plane, are known as 1.  Magnitude Sum of Two vectors Vector P and Vector q is given by r^2 =p^2q^22pqcos($) _____(i) here $ indicates angle between them We are given r=pq so Squaring both the sides we get r^2=p^2q^22pq _____(ii) From (i) and (ii) we can write p^2q^22pqcos($)=p^2q^22pq therefore 2pq=2pqcos($). Q if p , then q q , ifp p , only if q p implies q p is sufcient for q q is necessary for p q follows from p c Xin He (University at Buffalo) CSE 191 Discrete Structures 15 / 37 Terminology for implication Example Proposition p.

 Let the angle between two vectors P and Q be alpha and their resultant is R So we can write R^2=P^2Q^22PQcosalpha1 When Q is doubled then let the resultant vector be R_1, So we can write R_1^2=P^24Q^24PQcosalpha2 Again by the given condition R_1 is perpendicular to P So 4Q^2=P^2R_1^23 Combining 2 and 3 we get.  Two forces P and Q are in ratio `PQ=12` If their resultant is at an angle `tan^(1)((sqrt3)/(2))` to vector P, then angle between P and Q is A `tan^(1)((1)/(2)) ` B `45^(@) ` C `30^(@)` D `60^(@)`. In conditional statements, "If p then q" is denoted symbolically by "p q";.

P then q” or “p implies q”, represented “p → q” is called a conditional proposition For instance “if John is from Chicago then John is from Illinois” The proposition p is called hypothesis or antecedent, and the proposition q is the conclusion or consequent Note that p → q is true always except when p is true and q is false.
