Answer 1

Right option is (a) True

To elaborate: Fundamental of rubber engine sizing method is that we are using new design of engine. New design can be made as per our requirements. Rubber engine can be scaled according to our requirements and then the performance parameters are evaluated. Hence, rubber engine can be sized to meet our thrust requirements.
