Question

Which persuasive technique is used in this poster?

Answer 1

This poster clearly demonstrates the application of commercial advertising techniques to contribute to the war effort.

The graphic imagery is particularly forceful: a soldier exchanges a tool with the mechanic demonstrating team spirit and a sense of patriotism.  

The poster uses the incident of a fire to insist on the urgency and promote the efficiency in factories.  

On the red background, the message is negative (“Breakdowns”, “lose”) but on the blue background the message stays positive (“workmanship counts”) and the possessive OUR is printed in italics to focus on duty and patriotism.

Answer 2

Appeal to Trust, because this poster will make people believe what you are trying to say about the war breakdowns and they will share their point of view.
