Situation $3.$ The simple span in figure B$-001$ carries concentrated loads P and

Q$.$

If $P=9\mathrm{.}5kN,$ what value of $Q(kN)$ should be applied at the free end to

prevent deflection at $C?$

A$.2\mathrm{.}35$

C$.2\mathrm{.}22$

B$.1\mathrm{.}26$

D$.1\mathrm{.}98$

If $Q=8kN,$ what value of $P(kN)$ should be applied to prevent deflection

at $C?$

A$.29\mathrm{.}31$

C$.21\mathrm{.}05$

B$.19\mathrm{.}65$

D$.32\mathrm{.}40$

If the deflection at the free end is $7mm$ downwards, what should be the

equal values of the two concentrated loads $(kN)?$ Use EI $=24x{0}^{12}N-m{m}^2.$

A$.66\mathrm{.}10$

C$.68\mathrm{.}40$

B$.43\mathrm{.}28$

D$.40\mathrm{.}72$
