Homework Statement You are lost in a forest. You have become separated from your friend. At your eye level, only tree trunks block your view of distant parts of the forest (there are no leaves and branches at eye level to block your view, only tree trunks). The trees are spread randomly...

Homework Statement The ends of the slender bar remain in contact with their respective support surfaces. If end has a velocity in the direction shown, determine the angular velocity of the bar and the velocity of end. Answers: ω=1.394 rad/s VA=0.408 m/s down Homework Equations Va=Vb +Va/b...

my professor mentioned being able to obtain the mass flow rate from the problem statement and then using an energy balance to then find the final temperature in each tank. He also said the pressure is not equal in both tanks.

1. Homework Statement Two large, well-insulated tanks of 2m diameter and 5m in height are filled with air. One tank is initially at 1bar and 300oK and the other is at 10bar at 300oK. Determine the final temperature in both tanks if a valve connecting the two tanks is opened and the mass...

After converting r^3 from cylindrical to spherical I attained the value of (p^5)*sin(phi)^4, I still don't understand how to get the new limits of integration though

Homework Statement Convert the following integral to an equivalent integral in spherical coordinates. Do NOT evaluate the integral. ∫∫∫ r^3 dz dr dtheta limits of integration pi/4<theta<pi/2 0<r<2 0<z<√(2r-r^2) Homework Equations z=pcos(theta) r^2=x^2 +y^2 p^2=x^2 +y^2...
