For ladder to be in equilibrium there is net force and torque will be zero how can you justify that there is net force is zero?barryj said:
Yes this is for net torque ok but what about net force for transportation equilibrium? Look again force is balacing?barryj said:
Why you are thinking about only torque for translation equilibrium ΣFx=0,ΣFy=0 are these conditions satisfying?barryj said:
So do I.barryj said:
Because the normal and frictional forces from the ground will satisfy the linear equations, but we do not need to find them.Abhishek kumar said:
I know that.In question he had not mentioned frictional force that's why i asked.haruspex said:
It is posed as a statics question, and the wall is smooth, so there has to be adequate friction from the ground, but it is of no interest. The OP method was clearly appropriate.Abhishek kumar said:
But you have to mention that there is friction between ground and ladderharuspex said:
If the ladder can slip the question makes no sense. The failure to mention friction might irritate a perfectionist, but quibbling over that is of no help in answering the posted query.Abhishek kumar said:
The purpose of verifying a ladder against a wall force is to ensure that the ladder will not slip or fall while in use. This is important for the safety of the person using the ladder as well as for preventing any potential damage to the wall or surrounding area.
The factors that need to be considered when verifying a ladder against a wall force include the weight and load capacity of the ladder, the angle of the ladder against the wall, and the condition and stability of the wall itself. These factors will impact the amount of force that the ladder can withstand before slipping or tipping over.
The most commonly recommended angle for a ladder against a wall is a 75-degree angle. However, this may vary depending on the type and length of the ladder, as well as the surface it is being placed on. It is important to follow the manufacturer's instructions and safety guidelines when determining the appropriate angle for a ladder.
No, not all ladders are suitable for every type of wall or task. It is important to choose a ladder that is appropriate for the surface and job at hand. For example, a ladder with rubber feet may be better for use on a smooth surface, while a ladder with spikes may be necessary for use on grass or soft ground.
It is recommended to verify a ladder against a wall force before each use to ensure that it is safe and stable. However, if the ladder is being used for an extended period of time or for heavy-duty tasks, it may be necessary to periodically re-check and adjust the ladder's position and force against the wall.
