Part 2: a) You are investigating the electrical testing circuits and find that, in an inductive circuit, the relationship between instantaneous current 1' (amps) and the time t (secs) is given by: f = 2.1 (1 e'9t) You have been asked to determine the time taken for the current to change from 1 to B amps. b) The distance travelled by a flying UAV can be shown as, x in the following equation. Use the laws of logarithms to solve the equation for the distance travelled: 2X+1 = 3AX'5 c) The drive system of a conveyor used to transport the engine parts is made up of an open belt which passes over two pulleys. The pulleys have diameters of 200mm and 320mm respectively and the distance between centres is T mm. You have been asked to determine the length of the belt, using trigonometric techniques, assuming the belt is in tension. d) A cable is to be suspended across two machines. The machines are a distance L metres apart. The cable forms the shape of a catenary of the form y = c cosh (x/c) where x = L/2. You have been asked to determine the fixing point height (y) if the minimum clearance (c) is to be 3m at the centre of the catenary
