Show answer and explanation

Correct answer: (A) Limiting zone for prestressing; (B) Magnel's graph; (D) Load balancing method

Explanation

The limiting zone, Magnel's graph and the load balancing method are all used to make sure the stresses at transfer and under service load stay within the permitted limits. The Hoyer effect describes how prestress is transferred to the concrete by bond in pre-tensioned members, so it does not check stresses.
