A pre-stressed concrete beam has a width of 200 mm and an overall depth of 400 mm. The permissible stresses in tension and compression due to pre- stressing alone are 4 N/mm and 25 N/mm respectively. Find the required pre- stressing force in the tendon and the eccentricity of the tendon, if a straight tendon with a constant eccentricity is to be provided in the beam. No external load or self weight effect is to be considered.
