ΣFx=max
The Attempt at a Solution
I drew a free body diagram for the box and set up the equation to solve for θ, but I'm not sure how to do it without μ
Suraj M said:I don't think you need to substitute
##F_{friction}## with ##μ F_N##
They want you to use the frictional force they themselves have provided in the question.
In a way, your mistake is one that is reasonable to make.x2017 said:Oh my goodness I can't believe I missed that... Thank you!
ΣFx=max
mgx-Ffx=max
mgsinθ-Ffx=max
(100)(9.81)sinθ-490.5=(100)(0)
981sinθ=490.5
θ=sin-1(490.5/981)
θ=30°
Wow, that was an embarrassing mistake!
The angle at which a box will begin to slide depends on several factors, including the weight and mass of the box, the friction between the box and the surface it is resting on, and the force acting on the box (such as gravity).
Yes, there is a formula known as the "sliding angle" formula that can be used to calculate the angle at which a box will begin to slide. It takes into account the weight and mass of the box, the coefficient of friction between the box and the surface, and the force acting on the box.
The coefficient of friction is a measure of the amount of resistance between two surfaces in contact. The higher the coefficient of friction, the more difficult it is for the box to slide. Therefore, a higher coefficient of friction would result in a higher sliding angle.
Yes, the shape of the box can definitely affect the angle at which it will begin to slide. For example, a box with a wider base will have a lower sliding angle compared to a box with a narrower base, as the wider base provides more stability and resistance against sliding.
Understanding the sliding angle of a box is important in various industries, such as construction, engineering, and transportation. It can help in determining the stability of structures and vehicles, as well as ensuring the safety of workers and passengers. It is also useful in everyday tasks, such as packing and storing items to prevent them from sliding or tipping over.
