Why are the main support cables of the suspension cables designed to sag?

They can't be designed not to. Large cables and ropes are extremely different to stretch straight, because of their high weight-to-length ratio.

What is the main difference between an arch bridge and a suspension bridge?
Arch bridges are in the shape of an upside down "U" with mainly steel beans, while supension bridges have one or two Major verticle beams with strong wire connecting to the bridge.
What effect does gravity have on bridges?
The primary effect of gravity on a bridge is that it keeps it "in place" in the wind. The massive weight of the bridge is a key part of its structure and of its structural integrity. Certainly gravity acts to "pull the bridge down" in effect, but we use that to stabilize the structure, turning a "negative" into a "positive" in that light. Gravity transfers forces to the structures that support the bridge, and, in the case of (most) suspension bridges, hold the ends of the main cables to the massive blocks set to maintain the tension of those cables.
Why use a suspension insulator on 11kv electric power lines?
Suspension insulators are glass 'dish' insulators that are designed to take longitudinal strain -i.e. strain in the direction of the conductors. They are so-called, because they are suspended below the pole's crossarm. Suspension insulators, therefore, are used on terminal poles where the main strain on the crossarm is in the direction of the conductors, or on angle-poles where there is a sharp change in direction of the power line.
Is a suspension bridge better than a cable stayed bridge?
NOcable stayed bridge is more preferred because if one rope is broken in it then tension is distributed in all other and we get time to repair it that means no sudden failure in it where as in suspension bridge if main cable is cut than it will be destroyed immediately.regardsmukulmukul_ce@student.iitd.ac.in

What holds up large suspension bridge such as the Golden Gate Bridge?
The main cables which are securely anchored at each end and then drape over the towers. Smaller cables then hang from the main cables and suspend the roadway .
What do the towers in a suspension bridge support?
Cables are anchored in a concrete block (often thousands of tons of concrete) the cables then go up to the first tower, then to the second tower and down to another anchor block. The bridge road section hangs from these main cables by dozens of smaller cables. This way the downward pressure of weight is taken by the towers and helped by each anchor block
how suspension bridges load transfer to the ground?
Through the main cables being anchored in huge concrete blocks and the pylon towers resting on bedrock.
How long is the Manhattan bridge in miles?
1.3 milesThe Manhattan Bridge is a suspension bridge that measures 1470 feet long on the main span. The suspension cables are 3224 feet long and the total length of the bridge is 6855 feet.

What influenced the Golden Gate Bridge?
metal beams are place in the ground to support the golden gate bridge these beams are so strong so they can hold the support of the bridge and every thing else
What are the four main parts of the suspension bridge?
deck, span, abutment, cable, hanger, foundation, tower, and anchor
What is the main difference between front and rear suspension on vehicle?
The front suspension is steerable.
What are the main subwoofer cables?
The main subwoofer cables can go by quite a number of various names. The port name that they plug into is called RCA. One example of these cables is the Mediabridge Ultra Series.

How does the Golden Gate Bridge work?
The main cables are strung with vertical cables that attach to the deck. These cables support the deck of the bridge, transferring the weight to the towers at the end. The main cables continue past the tower, and are anchored past the far ends of the bridge. They are carefully balanced so that the force pulling inward on the towers is equal to the force pulling outward. As a result, the weight pulls directly down into the base of the tower. The towers can be fairly thin, since they aren't being pulled to either side. The deck can also be thin, since it is being supported by the cables.
