Please explain in detail! Thank you!
45° 450Solution
part E to H
Since all the surface are frictionless.
The contact force F exerted by lower sphere on the upper sphere is in 34 deg of horizontal.
Forces exerted by walls and floors are in the normal direction of them.
Equilibrium on the top force gives two equations
Fwr = F*cos 34 deg
F*sin 34 deg = m*g
equilibrium of forces on bottom sphere
Fwl = F*cos 34 deg
Ff = F*sin 34 deg + mg
Solving the above four equation gives
force by the bottom of the container
Ff = 2*m*g
force by the contact of esch other
F = mg/sin 34 deg
F = 1.788*m*g
force by left side of container
Fwl = F*cos 34 deg = 1.788*m*g*cos 34 deg
Fwl = 1.482*m*g
force by right side of container
Fwr = F*cos 34 deg = 1.482*m*g
