Calculatethe vorticity vector as a function of space (x, y, z).
Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
Consider the heat engine operating at steady state between the two thermal reservoirs shown at the right while producing a net power output of 700 kW. If 1000 kW of heat (Q̇H) is transferred to the heat engine from a thermal reservoir at a temperature of TH = 900 K, and heat is rejected to a thermal reservoir at a temperature of TL = 300 K, is this heat engine possible?

1.12 A disk of constant radius r is attached to a telescoping rod that is
extending at a constant rate as shown in Fig. P1.12. Both the disk
and the rod are rotating at a constant rate. Find the inertial
velocity and acceleration of point P at the rim of the disk.

Two different options A and B with brake pads for disc brakes are connected to the rope drum. The diameter of the rope drum is 150 mm. What distance must the pads B be at from the center of rotation to cover the same distance as A?A B- Width 50 mm - Width 60 mm- Evidence center 120mm - Construction power 900 N from rotation center.- Maintains a weight of 200 kgwhen the installation force is 1.4kN
(μ is missing from the data)M=μF(Ry-Ri)Right answer R=187 mm
