Rise of three-hinged Parabolic Arch Solution

STEP 0: Pre-Calculation Summary
Formula Used
Rise of the arch = (Ordinate of a point on arch*(Span of the arch^2))/(4*Horizontal distance from the support*(Span of the arch-Horizontal distance from the support))
f = (y*(l^2))/(4*x*(l-x))
This formula uses 3 Variables
Variables Used
Ordinate of a point on arch - Ordinate of a point on arch is the ordinate of any point along the central line of the arch. It basically gives the Equation for a three-hinged Parabolic arch. (Measured in Meter)
Span of the arch - Span of the arch is the horizontal distance between the two supporting members of an arch. (Measured in Meter)
Horizontal distance from the support - Horizontal distance from the support represents the horizontal distance from any support of the arch to the section being considered. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Ordinate of a point on arch: 1.5 Meter --> 1.5 Meter No Conversion Required
Span of the arch: 16 Meter --> 16 Meter No Conversion Required
Horizontal distance from the support: 2 Meter --> 2 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
f = (y*(l^2))/(4*x*(l-x)) --> (1.5*(16^2))/(4*2*(16-2))
Evaluating ... ...
f = 3.42857142857143
STEP 3: Convert Result to Output's Unit
3.42857142857143 Meter --> No Conversion Required
FINAL ANSWER
3.42857142857143 Meter <-- Rise of the arch

What is a three-hinged arch?

A three-hinged arch is a geometrically stable and statically determinate structure. It consists of two curved members connected by an internal hinge at the crown and is supported by two hinges at its base. Sometimes, a tie is provided at the support level or at an elevated position in the arch to increase the stability of the structure.

What makes arches different from other structures?

One of the main distinguishing features of an arch is the development of horizontal thrusts at the supports as well as the vertical reactions, even in the absence of a horizontal load. The internal forces at any section of an arch include axial compression, shearing force, and bending moment.
