Q3 (a) A timber floor joist is subjected to a uniformly distributed load. The joists are spaced 450 mm centres with effective span of 3.0 metres. Based on bending stress, suggest a suitable size of select grade Penaga at 18% moisture content, in accordance with MS 544: Part 2: 2001. Given, Variable action = 0.25 kN/m Permanent action = 1.** kN/m (** is the last two digits of your matric card number. For example, your matric card number is AF200102. Therefore ** is 02 and dead load is 1.02 kN/m). (15 marks)
