Calculating Minimum Diameter for Iron Bolt to Withstand Shear Forces

AI Thread Summary
To calculate the minimum diameter of an iron bolt that can withstand shear forces of 3200 N with a safety factor of 6.0, the shear strength of the material, which is 170 x 10^6 N/m², must be considered. The formula used is F/A, where F is the shear force and A is the cross-sectional area of the bolt. The area can be expressed in terms of the diameter (d) using the formula A = π(d/2)². By rearranging the equation and incorporating the safety factor, the minimum diameter can be determined. Understanding these calculations is essential for ensuring the bolt's integrity under shear loads.

I need help getting started on this.
Question:
An iron bolt is used to connect two iron plates together. The bolt must withstand shear forces up to about 3200 N. Calculate the minimum diameter for the bolt, based on a saftey factor of 6.0.
Here is what I know so far.
Shear Strength is 170 x10^6
F/A
I don't even know where to start? Do I need a mass?

Well, what have you done?. Remember the bolt is in simple shear (it cuts in 1 plane)
 
I don't understad what you just said. I'm not good with physics at all. Can you explain that to me please.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
