Drawbridges, such as this one at the tower of london, are raised and lowered by cable systems. now consider the drawbridge illustrated below wherein the nearly horizontal brown door is centered along the vertical brick wall, the door-wall angle is α = 75 o as measured relative to the black hinge axis, the tension (magnitude) in each cable is t = 400 n and the relevant dimensions are a = 360 cm, b = 140 cm, c = 550 cm and d = 310 cm. determine the resultant torque (magnitude) | ( m r ) a x i s | in nm that the two cables contribute to the moment about the hinge axis.

Asmall electric heater, immersed in 80g of water in a calorimeter of 40j/k raises the temperature from 10.5 degree celsius to 25 degree celsius in 12 minutes. using the same apparatus with 50g of oil instead of water, it is found that the temperature of oil rises from 7 degree celsius to 27 degree celsius in 10 minutes. find specific heat capacity of the oil.
