A slider-crank linkage has the given properties: r = 3 in., l = 12 in., and ω = 200 rad/sec at time t = 0. The initial crank angle is zero. Calculate the piston acceleration at t = 1 sec. Solve using both the exact solution and the approximate Fourier series solution. Compare the results and find the error.

You have 80 g of 60oc water and 80 g or 10oc water. what is the final temperature when the two are mixed? explain.

Auniform bridge, 20 m long and weighing 40000 n is supported by two pillars located 3.0 m from each end. if a 19600 n car is parked 8.0 m from one end of the bridge, how much force does each pillar exert?

In eq. (10.1) in the lab manual, the constant is 41.1 gm-cmsec in air. a piece of paper has a mass per unit area of approximately . if the frequency is 4.8 khz, what does theory predict for the ratio of the transmitted amplitude to the incident amplitude of the sound wave? (a sound wave is a pressure wave.)
