Find the length of the astroid x23+y23=a23.

While cutting a piece of paper, a person exerts the two indicated forces on a paper cutter. Reduce the two forces to an equivalent force–couple system at corner O and then specify the coordinates of the point P in the x-y plane through which the resultant of the two forces passes. The cutting surface is 30" x 30".Question 2: Replace the two forces from the original system with a single equivalent force R. This force will pass throught a point P in the x-y plane. Find the distances x and y.The new system looks like this. How big is the force R (enter a positive number) ? Find the distances x and y.

2. Draw the free-body diagram of the beam, which is pin supported at A and rests on the smooth incline at B.

How do you solve this

One a teeter-totter, Ole weighs 292# and is 17' from the center. Lena is 15' 8" from the center, they are equilibrium. How much does Lena weigh?

I have a cones geometry question.

A pipeline is to be fitted under a road within the perimeter of the theme park and can be represented on 3D Cartesian axes as below, with the x-axis pointing East, the y-axis North, and the z-axis vertical. The pipeline is to consist of a straight section AB directly under the road, and another straight section BC connected to the first. All lengths are in metres. Refer to the attached image and provide the following: 1- Calculate the distance AB The section BC is to be drilled in the direction of the vector 3i+4j+k 2-Find the angle between the sections AB and BC. The section of pipe reaches ground level at the point (a,b,0). 3-Write down a vector equation of the line BC. Hence find a and b.
