Four strain gauges, with specification given below, are available to measure the torque on a cylindrical shaft 4 cm in diameter connecting a motor and load. (a) Draw clearly labelled….
Find the numerical value of CF for this type of spring and compare it with the value .
1. Considering a solid square bar of steel with side-dimension s and length-dimension L, would you predict that more elastic strain energy could be stored in the bar (without yielding) by using it as a direct tension spring axially loaded in the L-direction, or by using it as a cantilever-bending spring loaded perpendicular to the L-direction? Make appropriate calculations to support your prediction.
2. a. Write the equations from which the form coefficient CF may be found for a simply supported center-loaded multileaf spring.
b. Find the numerical value of CF for this type of spring and compare it with the value .
