Terrys suit can smash through the walls of the batcave, as demonstrated in the episode where it was possessed. I dont think Tommy ever displayed strength like that.
Also I have often wondered if power rangers strength feats were due to the suits or just the strange physics that govern the rangers universe. Case in point, air in space and the rangers fighting robots while unmorphed.
Although Terry has been overpowered by normal humans while in the suit but I blamed that on plot convenience.
Tommy did use a tree trunk like it was a staff to beat down a few puddies when he was the Green Ranger. Lol, that is the only thing I can remember in terms of showing off shear strength.
