Answer:
True
Explanation:
For point in xz plane the stress tensor is given by![\left[\begin{array}{ccc}Dx_{} &txz\\tzx&Dz\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7DDx_%7B%7D%20%26txz%5C%5Ctzx%26Dz%5C%5C%5Cend%7Barray%7D%5Cright%5D)
where Dx is the direct stress along x ; Dz is direct stress along z ; tzx and txz are the shear stress components
We know that the stress tensor matrix is symmetrical which means that tzx = txz ( obtained by moment equlibrium )
thus we require only 1 independent component of shear stress to define the whole stress tensor at a point in 2D plane

Its change in temperature in pipes depends on rate heads and loss in pipes owing to pipe flow, contractual loss, etc.
The temperature change thus relies on V1 v2 p d D L.
When the applied force is larger than the maximum force of static friction the object will move. ... The magnitude of the kinetic friction is: fk=μkN. Remember that static friction is present when the object is not moving and kinetic friction while the object is moving.
Answer:
0.163 MW
Explanation:
To get the minimum rate of energy rehection by heat transfer to cold reservoir, it implies that the power cycle operates in reversible cycle. The efficiency of reversible cycle whose value will be same as efficiency of power cycle will be given by
Efficiency of reversible cycle
n= (Th-Tc)/Th where T represent temperature, n efficiency, subscripts h and c hot and cold respectively
Substituting 500 and 310 for hot and cold temperatures respectively then efficiency
n=(500-310)/500=0.38
Efficiency of power cycle, n= Power output/Qh
Qh= 0.1/0.38= 0.263
Net power output, W= Qh- Qc
Qc=Qh-W= 0.263-0.1=0.163 MW
