Which statement below best captures how complex texts should be utilized in the classroom? Answer a). Complex texts should be the center of instruction. All students who have demonstrated the ability to engage in grade-level complex text should have opportunities to do so. b). Grade-level complex texts should be the center of instruction. Text sets that represent are utilized in service of building knowledge, strengthening vocabulary, and exposing students to a range of text types. c). Students will benefit from engaging in a wide range of unrelated complex, grade-level texts. In high-stakes testing, students need to be prepared for any given text type or topic. d). Complex texts should be the center of instruction, except for students who have disabilities or are English Language Learners. In this case, lower-level texts that have similar topical information should replace grade-level complex text.

A V-belt, having a mass of 0.25 kg/m, transmits power between two pulleys of diameters 100 mm and 200 mm. The distance between their centres of rotation, $b$, is 1000 mm. The belt is installed with an initial tension of 400 N and the coefficient of friction between the belt and the pulleys is 0.3. The groove angle $\gamma$ is 40$^\circ$ and the larger pulley is driven at 750 rpm. Determine: a) The angle of lap for each pulley b) The belt tensions at 750 rpm c) The power transmitted d) Assuming the criterion for maximum power calculate the answers to parts (b) and (c) again and comment on the results. e) Discuss the initial tension requirements for the operation of a Vee belt. What bearing do the results of part (d) have?
