Figure P10.18 shows the drive train of a bicycle that has wheels 67.3 cm in diameter and pedal cranks 17.5 cm long. The cyclist pedals at a steady cadence of 76.0 rev/min. The chain engages with a front sprocket 15.2 cm in diameter and a rear sprocket 7.00 cm in diameter. Calculate (a) the speed of a link of the chain relative to the bicycle frame, (b) the angular speed of the bicycle wheels, and (c) the speed of the bicycle relative to the road. (d) What pieces of data, if any, are not necessary for the calculations?
Block 3 Lecture 4 - Cerebrum 1. List the major lobes of the cerebrum Frontal lobe, Temporal lobe, Occipital lobe, Parietal lobe 2. Describe what is meant by “hemispheric lateralization” and name two functions lateralized to the left and right hemisphere Opposite sides of the brain are different functionally (not structurally). “Brain sided-ness” does not always correspond to “handedness” Right side (creative side) main function - Face recognition Left side (analytical side) main function - language 3. Describe what is meant by a “topographic map” and name cerebral functions that are mapped Neurons in the primary motor cortex are arranged by the muscles they control. Neurons in the primary somatosensory cortex are arranged according to the body region t
