, , , and and will get +1 mark; choosing ONLY The vertical component of reaction force at O does not depend on

, and and will get +2 marks; choosing ONLY and will get +1 mark; choosing ONLY The horizontal component of reaction force at O is equal to W for = 0.5

and The tension in the rope is 2W for = 0.5

. ONE OR MOER THAN ONE of these four option(s) is (are) correct answer(s). • For each question, choose the option(s) corresponding to (all) the correct answer(s). • Answer to each question will be evaluated according to the following marking scheme: Full Mark +4 If only (all) the correct option(s) is(are) chosen; Partial Marks +3 If all the four options are correct but ONLY three options are chosen; Partial Marks +2 If three or more options are correct but ONLY two options are chosen, both of which are correct; Partial Marks +1 If two or more options are correct but ONLY one option is chosen and it is a correct option; Zero Marks 0 If unanswered; Negative Marks -2 In all other cases. • For example, in a question, if are the ONLY three options corresponding to correct answers, then choosing ONLY will get +4 marks; choosing ONLY will get +2 marks; choosing ONLY will get +2 marks; choosing ONLY will get +1 mark; choosing no option(s) (i.e. the question is unanswered) will get 0 marks and choosing any other option(s) will get -2 marks. One end of a horizontal uniform beam of weight W and length L is hinged on a vertical wall at point O and its other end is supported by a light inextensible rope. The other end of the rope is fixed at point Q, at a height L above the hinge at point O. A block of weight W is attached at the point P of the beam, as shown in the figure (not to scale). The rope can sustain a maximum tension of . Which of the following statement(s) is(are) correct? The rope breaks if > 1.5
