Answer оn fоliо pаper 2(c)(ii) The Young modulus E of the wood is given by W is the weight of the loаd = 5.80 N l is the length from the bench to the end of the metre rule = 0.800 m w is the width of the metre rule = 3.00 cm t is the thickness of the metre rule = 5.00 mm The mаnufacturer of the metre rule gives the value of E for the wood as 10.8 × 109 Pa ± 4.0% Deduce whether the student’s results agree with this value for the Young modulus (4)
