Board Techn. Paper No. 1. 2 The total strain energy of the beam is made up of three components due to bending, torque and shear. 1939 Jrnl. Amer. Chem. Soc. 61 1871/2 The relative heats of hydration may be employed to evaluate the strain energy in cyclopentene only after correction has been made for these steric effects. 1976 A. L. Ternay Contemp. Org. Chem. vii. 197 The cyclopentane ring is puckered and..the cyclohexane ring exists largely in the chair form. If these compounds did not adopt these geometries, their strain energy would increase. 1977 Willems & Lucas Struct. Analysis for Engineers (1978) iii. 34 For the purposes of this text..all work done by external actions Ai acting through corresponding displacements Di will be converted into kinetic and strain energy, and no energy losses will occur. < as lemmas |
