A hole is to be drilled in the plate at A. The diameters
Chapter 2, Problem 2.95(choose chapter or problem)
A hole is to be drilled in the plate at A. The diameters of the bits available to drill the hole range from \(\frac{1}{2} \text { to } 1 \frac{1}{2} \text { in. in } \frac{1}{4} \text {-in. }\) increments. If the allowable stress in the plate is 21 ksi, determine (a) the diameter d of the largest bit that can be used if the allowable load P at the hole is to exceed that at the fillets, (b) the corresponding allowable load P.

QUESTION:
A hole is to be drilled in the plate at A. The diameters of the bits available to drill the hole range from \(\frac{1}{2} \text { to } 1 \frac{1}{2} \text { in. in } \frac{1}{4} \text {-in. }\) increments. If the allowable stress in the plate is 21 ksi, determine (a) the diameter d of the largest bit that can be used if the allowable load P at the hole is to exceed that at the fillets, (b) the corresponding allowable load P.
ANSWER:
Step 1 of 11
First we will compute the allowable load based on the given geometry of the member. Then, for different hole diameters, we will compute the allowable load.
