How do you calculate forging reduction ratio?
reduction ratio= initial cross sectional area/final cross sectional area
What is a component form?
The component form of a vector lists the horizontal and vertical change from the initial point to the terminal point. * * * * * The axes need not be perpendicular to one another. They just need to be non-parallel.
A steel rod has a length of exactly 0.2 cm at 30 C What will be its length at 60 C?
The initial length is 0.2 cm Initial temperature is 30 degrees C and final temperature is 60 degrees C. he difference in temperature is 30 degrees. Let "e" be the linear coefficient of expansion of the steel rod in cm per degree C (you can find this from the specifications for the particular steel), then the expansion is 0.2 x e x 30 cm To find the total new length we have to add the original length which is 0.2 cm Hence new length is 0.2 + (0.2 x e x 30) cm And that is (0.2) x (1 + e x 30) cm
A man finds the angle of elevation of the top of a tower to be 30 degrees He walks 85 meter nearer the tower and finds its angle of elevation to be 60 degrees What is the height of the tower?
L/(L-85) = tan60/tan30 = 3 (L = initial distance of man from base of tower)L = 3L-255 so 2L = 255 and L = 127.5 giving height = 127.5 tan30 = 73.6 m
What is the initial line of polar coordinates?
The equivalent of the x-axis
What do you need to know to be able to determine how far a projectile travels horizontally?
To determine how far a projectile travels horizontally, you need to know the initial velocity of the projectile, the angle at which it was launched, and the acceleration due to gravity. Using these values, you can calculate the time of flight and then multiply it by the horizontal component of the initial velocity to find the horizontal distance traveled.
What is the horizontal distance traveled by a projectile?
The horizontal distance traveled by a projectile is determined by the initial velocity of the projectile, the angle at which it was launched, and the time of flight. It can be calculated using the equation: horizontal distance = (initial velocity * time * cosine of launch angle).
A projectile is thrown with an initial velocity which has a horizontal component of 4 m s What will be its horizontal speed after 3s?
The horizontal speed of the projectile remains constant as there is no force acting in the horizontal direction to change it. Therefore, the horizontal speed of the projectile after 3 seconds will remain at 4 m/s.
What do the horizontal motions of a projectile have in common?
The horizontal motions of a projectile are independent of its vertical motion. This means that the horizontal velocity remains constant and unaffected by gravity. Additionally, the horizontal distance traveled by a projectile is determined by the initial horizontal velocity and the time of flight.
What is half projectile?
A half projectile refers to the projectile motion of an object where it is launched at an angle of 45 degrees to the horizontal. This angle maximizes the range of the projectile for a given initial velocity, making it travel the furthest distance before hitting the ground. The path of the projectile is a parabolic curve.
What are the angles for which the range of projectile is the same?
For a projectile launched at an angle θ, the range is the same for angles of θ and (90-θ) degrees. This is because the horizontal and vertical components of the initial velocity are the same for these angles, resulting in the same horizontal range.
Which information is needed to determine the horizontal distance a projectile travels?
-- the initial horizontal speed of the projectile -- the time it remains in flight before it hits the ground
What is the horizontal displacement of a projectile?
it depends on the gravitational force of attraction of earth and air resistance. if we are neglecting air resistance, the max.horizontal distance is according to this formulae, V0/2 * sin (2theta) where V0 is the initial velocity theta is the angle with x axis and the projection.
What is the formula for a horizontal launched projectile?
The formula for the horizontal distance traveled by a horizontally launched projectile is: range = initial velocity * time. This formula assumes that there is no air resistance and that the projectile is launched horizontally.
What do need to know to determine how far projectile travels horizontally?
To determine how far a projectile travels horizontally, you need to know the initial velocity of the projectile, the angle at which it was launched, and the acceleration due to gravity. Using these values, you can calculate the horizontal distance traveled using the projectile motion equations.
What is the proof that 45 degrees provides the maximum range for projectile motion?
The proof that 45 degrees provides the maximum range for projectile motion is based on the fact that at this angle, the horizontal and vertical components of the initial velocity are equal. This results in the projectile traveling the farthest distance before hitting the ground.
How can one determine the launch velocity of a projectile?
To determine the launch velocity of a projectile, you can use the projectile motion equations. By measuring the initial height, horizontal distance traveled, and the angle of launch, you can calculate the launch velocity using trigonometry and kinematic equations.
