ASO Regular Concert #94!

ASO Regular Concert #94!I'm happy to be able to enjoy ASO regular concert # 94 for the first time in two years tonight.
I was very impressed to find that the instrument being played was visible near at hand because the seat was in the center of the front of the first floor.
In the first half, Liszt's symphonic poem Les Preludes showed a well-balanced balance of his rhythm harmony melody and remarkable progress over the years in his ASO. I appreciate the conductor, Kazufumi Yamashita!
In the 4th movement of Mahler Symphony No. 5 in C sharp minor in the latter half, there was a rare harp performance, and the sound of a large, large-capacity stringed instrument that I listened to for a while with a wonderful tone was unique and peaceful~.
I'm looking forward to the autumn concert, thank you!

Toe-in?

Toe-in?Matching the direction of the vector sum of the left and right front wheels with those of the rear wheels is called thrust adjustment.
In wheel alignment it is commonly known as camber, castor and toe, but the steering structure is more complicated for turning action.
Steering construction has a lot of three-dimensional ingenuity to make it easy to turn on the front wheels that control steering and to ensure straightness.
An angle is provided on the rotation axis of the hub during steering, and this is called the kingpin angle. In the case of the strut mechanism, it is called the strut axis inclination, SAI. This is the first adjustment standard for the front toe-in amount, which greatly affects the steering feeling when turning.
Here, a concept that has been misunderstood for a long time has been said that "front toe-in is given to ensure straightness", but this is a big mistake.
As a matter of fact, as you can see by actually trying it, it has better straight-line stability in toe-out than in toe-in under negative camber conditions of about 20 minutes at the front.
Again, we set the front toe-in adjustment criteria to zero and we observes the 20 degree rotation angle difference and make fine adjustments if necessary.
"Not to ensure straightness", "But to establish 20 degree rotation angle difference."
When going straight, it is the centrality of the Rear wheels, that is, the thrust, which determines the driving direction of the car, Not the front wheels.
When the direction of the vector sum of the left and right front wheels and the direction of the vector sum of the left and right rear wheels match, "When the Thrust Angle is Zero", the geometric Axsle construction keeps the car going straight without operating the steering wheel.
