Mathematics QUESTION #963

Question 11

In a group of 3 girls and 4 boys, there are two boys $B_1$ and $B_2$. The number of ways in which these girls and boys can stand in a queue such that all the girls stand together, all the boys stand together, but $B_1$ and $B_2$ are not adjacent to each other, is:

96
144✔️
120
72

Correct Answer Logic:

Girls together: $3!$ ways. Boys together: $4!$ ways. Two blocks arranged: $2!$ ways. Total $= 2! \times 3! \times 4! = 2 \times 6 \times 24 = 288$. Cases where $B_1, B_2$ adjacent: treat them as one unit → $2! \times 3! \times 3! \times 2! = 144$. Required $= 288 - 144 = 144$.

Question 12

The Duhamel integral gives the response of an undamped SDOF system to an arbitrary forcing function $F(t)$ as:

$x(t) = \frac{1}{m\omega_n}\int_0^t F(\tau)\sin[\omega_n(t-\tau)]\,d\tau$ plus homogeneous solution✔️
$x(t) = \frac{1}{k}\int_0^t F(\tau)\,d\tau$
$x(t) = \int_0^t F(\tau)\cos[\omega_n(t-\tau)]\,d\tau$
$x(t) = F(t)/k$

Correct Answer Logic:

The Duhamel (convolution) integral for an undamped SDOF system: $x(t)=\frac{1}{m\omega_n}\int_0^t F(\tau)\sin[\omega_n(t-\tau)]d\tau$ plus the free-vibration homogeneous solution from initial conditions.
