**1. Draw Shear force and bending moment diagram for the following beam.**

**2. Find the axial force for the member AB and AC**

**3. A rectangular column of 15” x 15” section has reinforcement of 8 no. 9 bars. If the value of f’c is 3000 psi and fy is 60000 psi, find the ultimate design axial load of the column with zero eccentricity.**

**4. Write down the standard value of the following parameters.**

__Solution:__

Parameters | Bangladesh Standard | WHO standard |

i) Arsenic | 0.05 | 0.01 |

ii) BOD_{5} (20^{o}C) | 0.2 | 0.2 |

iii) Iron | 0.3-1.0 | 0.3 |

iv) Turbidity | 10 JTU/NTU | 5 JTU/NTU |

v) TDS | 1000 | 1000 |

**5. A falling head permeability was performed in a permeameter with an inside diameter of 5 cm. The inside diameter of standard pipe was 2 mm. The sample had a length of 8 cm. During period of 6 min, the head on the sample decreased from 100 to 50 cm. compute the value of K.**

**6. The sign shape for (i) Mandatory sign (ii) Cautionary sign (iii) Information or Guide sign.**

**7. Find space and time mean speed for the values of 55, 60, 45, 95 and 60 mile/hr.**

**9. Find the fineness modulus from the following sieve.**

Sieve Size | Materials retained (gm) |

#4 | 0 |

#8 | 0 |

#16 | 6 |

#30 | 40 |

#50 | 100 |

#100 | 323 |

Pan | 31 |

Total | 500 |

__Solution__

Sieve Size | Materials retained | % Retained | % Cumulative Retained |

#4 | 0 | 0 | 0 |

#8 | 0 | 0 | 0 |

#16 | 6 | 1.2 | 1.2 |

#30 | 40 | 8 | 9.2 |

#50 | 100 | 20 | 29.2 |

#100 | 323 | 64.6 | 93.8 |

Pan | 31 | 6.2 | 100 |

Total | 500 |

FM = (1.2 + 9.2 + 29.2 + 93.8)/100 = 1.33
