A = 45 kN a = 60° B = 20 kN ẞ = 30° Problem:M1.1 You and your friends are on an archaeological adventure and are trying to disarm an ancient trap to do so you need to pull a log straight out of a hole in a wall. You have 1 rope that you can attach to the log and there are currently 2 other ropes and weights attached to the end of the log. You know the force and direction of the ropes currently attached are arranged as shown below what is the magnitude and direction 'e' of the minimum force you need to apply to the third rope for the force on the log to be in direction of line 'a'? What is the resultant force in direction 'a'? a ////// //////

- 13- 3. Shastri recalled reading that for an ideal transformer, "the ratio of the primary voltage to the secondary voltage is equal to the ratio of the secondary current to the primary current." Plan and design an experiment to investigate whether the statement above is true. (8) • With the aid of a fully labelled circuit diagram, describe a procedure which can be used to investigate whether the statement is true. The circuit diagram must include the following components: A variable AC voltage supply • AC voltmeters • AC ammeters A transformer with adjustable turns ratio Connecting wires • ° A load resistor
