They are balanced by a force of 130 N. The magnitude of Q is a) 60 N b) 80 N c) 100 N d) 120 N Ans: d 2. If the resultant of two forces has the same magnitude as either of the force, then the angle between the two forces is a) 30° b) 45° c) 60° d) 120° Ans: d 3. A rod AB carries three loads of 30 N, 70 N and 100 N at distances of 20 mm, 90 mm and 150 mm respectively from A. Neglecting the weight of the rod, the point at which the rod will balance is a) 109.5 mm from A b) 119.5 mm from A c) 125.5 mm from A d) 132.5 mm from A Ans: a 4. The angles between two forces to make their resultant a minimum and a maximum respectively are a) 0° and 90° b) 180° and 90° c) 90° and 180° d) 180° and 0° Ans: d 5. When two forces, each equal to P, act at 90° to each other, then the resultant

Simple Definition of   arch . : A usually curved part of a structure that is over an opening and that supports a wall or other weight above the opening. : The raised area on the bottom of the foot that is formed by a curved section of bones. : Something that has a curved shape. Types of arches based on shape, material of construction, workmanship and number of centers are discussed here. An arch is constructed in curved shape due to which loads from above is distributed to supports (pier or abutment). Types of Arches Arches are classified based on: 1.    Shape 2.    Number of Centre’s 3.    Workmanship 4.    Materials of construction Types of Arches based on shape: Based on the shape of construction arches are classified into 10 types and they are discussed below. Flat Arch ·         For flat arch, the intrados is apparently flat and it acts as a base of equilateral triangle which was formed by the horizontal angle of 60 0  by skewbacks. ·         Even though
