In this paper, we examine a first-year torque and angular acceleration problem to address a possible use of the forelimbs of Tyrannosaurus rex. A 1/40th-scale model is brought to the classroom to introduce the students to the quandary: given that the forelimbs of T. rex were too short to reach its mouth, what function did the forelimbs serve? This issue crosses several scientific disciplines including paleontology, ecology, and physics, making it a great starting point for thinking “outside the box..." Lipkin and Carpenter have suggested that the forelimbs were used to hold a struggling victim (which had not been dispatched with the first bite) while the final, lethal bite was applied. If that is the case, then the forelimbs must be capable of large angular accelerations α in order to grab the animal attempting to escape. The concepts of the typical first-year physics course are sufficient to test this hypothesis... Naturally, student love solving any problem related to Tyrannosaurus rex.
In October 1947, the directors of J. Lyons & Co (think - teashops, nippies, bakeries, ice-creams, steakhouses, hotels, Wimpy Bars and Dunkin' Donuts), decided to take an active role in promoting the commercial development of computers. In 1951 the LEO I computer was operational and ran the world's first regular routine office computer job.
