block: W=15lb
wise: d=25mils
bar: initial angle =40\deg
AD is vertical
(You may assume that the block is rigid-i.e, remains straight.)
(a) find the normal stress \sigma in the wire
(b) if the allowable normal stress in the wire is \sigma _(allow )=35ksi, what
is the max permissible weight, W_(max ), of the block?
(c) if the 15 lb block causes the wire to elongate so that the bar
makes a final angle of 39\deg , find the normal strain \epsi on AB and AD remain the same length
Please help me solve this problem
