When you stand on ice, the two forces acting on you are gravity pulling you downward towards the center of the Earth and the normal force exerted by the ice pushing upward on your feet to support your weight and prevent you from sinking.
Upward force, used to counter the downward force of gravity acting on the climber. Precisely the same force used when walking up a flight of stairs. Provided in both cases by the climber's muscles.

Dynamic Load The "load" is the total force and weight that a structure such as a bridge is designed to withstand. For a bridge, the total load includes the "dynamic" loads of traffic, people, wind, snow, and ice and the "static" load of the bridge's own weight.
Yes Japan and Korea did have a land bridge in the Ice Age.
Cos they de-ice it.
Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.
Yes, a hockey puck sliding across the ice at a constant speed is in equilibrium. The forces acting upon it are balanced, with no net force causing acceleration.
The Beringia land bridge and ice bridge are not the same. The Beringia land bridge refers to a former land connection that existed between Siberia and Alaska during the last Ice Age, allowing animals and humans to migrate between Asia and North America. The Beringia ice bridge, on the other hand, is a theory that suggests that during certain periods of glaciation, sea ice in the Bering Strait may have connected the two continents, facilitating migrations.
If you are referring to the Bering strait land bridge, it wasn't made but was part of the earth. It was an ice bridge.
