A 3-lb collar can slide on a horizontal rod which is free to rotate about a vertical shaft. The collar is intially held at A by a cord attached to the shaft. A spring constant of 2 lb/ft is attached to the collar and to the shaft and is undeformed when the collar is at A. As the rod rotates at the rate ThetaDot=16 rad/s, the cord is cut and the collar moves out along the rod. Neglecting friction and mass of the rod, determinea)the radial and transverse components of the acceleration at Ab)The acceleration of the collar relative to the rod at Ac)the transverse component of the velocity of the collar at B
What tube diameter is required for the model if dynamic similarity is to be maintained between model and prototype?
The heat transfer coefficient in the oven is 25W/m^2K. Calculate rate of heat transfer per m^2 area.
The main elevator A of the CN Tower in Toronto rises about 349 m and for most of its run has a constant speed of 22 km/h. Assume that both the acceleration and deceleration have a constant magnitude of g/3 and determine the time duration t of the ..
a closed rigid tank whose volume is 1.5 m3 contains refrigerant 134a initially a two phase lipuid-vapor mixture at 10c.
Remember that velocity is a vector quantity so find the magnitude of the average velocity and the angle of average velocity from the horizon
A hydraulic cylinder is 100mm diameter and is fed by a pipe 15mm in diameter. If the piston in the cylinder moves forward at a rate of 0.2ms^1
The piston is now unlocked so it is free to move, and it conducts heat so the air comes to a uniform temperature . Find the mass in both A and B, and the final T and P.
If the rod experienced 28% uniform strain, calculated the load at the onset of necking.
plot your results determined in the previous part. (c) Calculate the values of n and C in the Taylor equation solving simultaneous equations.
If the critical resolved shear stress is 10 MPa, what is the yield strength?
the collar has a mass of 20kg and is supported on the smooth vertical rod. the attarched springsare undeformed when d=0.5m determine the speed of collar after the applied force F=100N causes it to be displaced so that d=0.3m when d=0.5m, the colla..
