Is ladder leaning with wall in equilibrium?
No, a ladder leaning against a wall is not in equilibrium. Equilibrium would occur if the forces acting on the ladder were balanced, but in reality, the ladder is subject to gravitational force and may slide or topple over if not properly stabilized.
Simple machine is a ladder?
i have no idea!! I would say, yes as a ladder makes work easier. It is simple as to not have moving parts. Sq-beats
An 80kg man is 14 of a way up a 10m ladder that is resting against a smooth frictionless wall What is the friction force if the ladder weighs 20kg and makes an angle of 60 degrees?
The ladder's weight does not affect the friction force between the ladder and the wall. The friction force is the horizontal component of the normal force acting on the ladder, which is equal to mass * gravity * cosine(angle). In this case, it would be (80 kg + 20 kg) * 9.81 m/s^2 * cos(60 degrees).
What example evaporation is not useful to us?
Evaporation in a puddle in a deserted area where there is no immediate need for the water evaporating would be an example of evaporation that is not useful to us.
What other experiments would a spectophotometer would be useful?
A spectrophotometer would be useful in experiments involving determining the concentration of a solution by measuring its absorbance, studying the kinetics of enzyme reactions by monitoring changes in absorbance over time, and identifying unknown substances by comparing their absorbance spectra to known compounds.
Would it be smart for someone who is standing at the top of a ladder to make a lateral move?
No
Why a ladder would be useful if you had to rescue someone from an icy pond?
It could help spread the weight of the rescuer, give a easy to grip device for the rescued, and if shoved downward could even provide a way to climb out of the water.
How would someone practice ladder safety?
A way to practice ladder safety is to read all instructions that come with the ladder. This can include selecting the right ladder for the task at hand and also making sure the weight limit is observed.
Why does lying on a ladder help you to reach someone trapped in thin ice?
If you laid the ladder flat on the ice and wanked on the ladder rather than the ice, then your weight would be spread over a much larger area than that of just your feet. It would then be less likely that you would break the ice yourself.
Where can one purchase a ladder for a bookcase?
There are many places one can purchase a ladder for a bookcase. The most reliable online outlet for purchasing this item would be Amazon. You can also visit stores such as target or Walmart. There is also an episode on "This Old House" that might be useful in constructing your own ladder for a bookcase.

A ladder is leaning against a wall if you were going to climb the ladder are you better off if there is no friction between the ladder and the wall or ladder and the floor?
No. if the floor is smooth you must have friction between the ladder and the floor, or the ladder would just slide away. Technically you could do without friction between wall and ladder, but even that can be helpful in preventing the ladder from going sideways.
