Answer:
Explanation:
The shear stress due to torque can be calculed by using the following model:
The maximum torque on the section is:
The Torsion Constant for the circular tube is:
Now, the require output is computed:
Answer:
120 N
Explanation: First we shoud consider the forces acted on a tree
Friction foce - acting opposite to the moving direction
Weight - Directly acting downwards
Reaction - Directly acting on upwards
For minimum required force should be equal to the friction force
F = μ R
F = 0.5×480
= 120N
Answer:
There are Two Major Branches of Physics that are Modern and Classical Physics. Further physics sub branches are electromagnetism, Mechanics, Thermodynamics, Optics.
Answer:
2.8A
Explanation:
To calculate the total amplitude (when both pulses meet), we need to add up the amplitudes of each pulse. Since A is the amplitude of the first pulse, and we can call B the amplitude of the second pulse and C the total amplitude, we have that A+B=C=3.8A, which means that B=3.8A-A=2.8A, which we have already said is the amplitude of the second pulse.
