00:01 In this question, we have to find the maximum force speed that can be applied so that it is not the stress that not exceeds the allowable stress of 150 megapastal.
00:16 So first, there are two points that could be failure.
00:24 First is the fillet point and the second is the whole point.
00:28 So for the fillet, we have to find the ratio k from the bill over h is 60 over 30 that is 2 and r over edge which is 15 and edge is 30 which is 15 and edge is 30 is 0 .5 so from the textbook k is 1 .4.
00:56 Now, have that the allowable stretch is equal to k times the average stress...
