2 parallel rods 8m apart are yield together by a steel bag 25mm passing through metal plate and nuts
at each other end. The nuts are screwed up to
the plate while the bar is at the
temperature of 150°C . Find the pull force
Converted
by the bar
the bar after
after it have pulled
at 40°C.
a. If the walls do not yield
b. If the total yielding at the two ends.​

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes.t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
