Question Solved1 Answer 3.16 A measuring system has a natural frequency of 0.5 rad/s, a damping ratio of 0.5, and a static sensitivity of 0.5 m/V. Estimate its 90% rise time and settling time if F(t)=2 U() and the initial condition is zero. Plot the response y(t) and indicate its transient and steady responses. 3.17 Plot the frequency response, based on Equations 3.20 and 3.22, for an instrument having a damping

1. Find the pressure due to a column of mercury 80 cm high. 2. A rectangular tank 6 x 8 ft is filled with a gasoline to a depth of 80 ft. The pressure at the gasoline is 14.7 psi. Find the pressure at the bottom of the tank and force exerted on the bottom. 3. A 130 lb woman balances on the heel of her right shoe which is 1 in radius. How much pressure does she exert on the ground?4. An amount of heat equal to 2500 J is added to a system, and 1800 J of work is done on the system. What is the change in internal energy of the system? 5. Determine the change in internal energy of 1.0 L of water at 100 deg C when it is fully boiled, which results in 1671 L of steam at 100 deg C. Assume the process is done at atmospheric pressure. 

4. A 900-mm strip of steel is bent into a full circle by two couples applied as shown. Determine (a) the maximum thickness of the strip if the allowable stress of the steel is 420 MPa, (b) the corresponding moment M of the couples. Use E = 200 GPa. M M 8 mm - 900 mm 4.

Two stones are separated by a vertical distance y (in meters) from each other. One stone is thrown down with an initial velocity v01 = -35 m/s and the other is thrown up from the ground with an initial v02 = 17 m/s at the same time the other is thrown. How far, in meters, must they be separated so they hit the ground at the same time? What is the impact velocity, in meters per second, of the first stone? What is the impact velocity, in meters per second, of the second stone?
