Answer:
Explanation:
The normal force exerted on the car by the walls of the cylinder at the bottom of the vertical circle will be such that when substracted to the weight it must give the centripetal force, since at that point on the vertical
We also know that the equation for the centripetal force is:
Mixing both equations we get:
Which for our values means:
Answer:
19.5324 MPa
Explanation:
Information provided
Angle between the normal to the slip plane with tensile axis,
Angle by slip direction with tensile axis,
Critical resolved shear stress,
Applied stress
Shear stress at slip plane
hence crystal won’t yield
Applied stress, for crystal to yield is given by
Explanation:
Given that,
Radius of the coil, r = 4.2 cm
Number of turns in the coil, N = 500
The magnetic field as a function of time is given by :
Resistance of the coil, R = 640 ohms
We need to find the magnitude of induced emf in the coil as a function of time. It is given by :
Hence, this is the required solution.
