The hoist shown in figure is constructed using two wooden bars with modulus of elasticity E = 1800 ksi and allowable stress of Gallow
The hoist shown in figure is constructed using two wooden bars with modulus of elasticity E = 1800 ksi and allowable stress of Gallow = 5 ksi. For a factor of safety of K= 2.5, determine the maximum permissible weight W that can be lifted using the hoist for the case of L=60 in. Note that 1 ksi = 6.89 MPa. | B B A- 30 L (ft) P = WY C W 4 in 5 in Cross section AA Cross section BB
