Part A

The beam is constructed from three boards. The allowable shear stress that the wood can sustain is ${}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=500.$ Each nail can resist a shear force of $400lb.($Figure $1)$

Determine the maximum shear $V$ that the beam can support.

Express your answer in kilopounds to three significant figures.
