A medieval city has the shape of a square and is protected by walls of length 500m and height 15m (assume zero width). You are the commander of an attacking army and the closest you can get to the wall is 100m. Your plan is to set fire to the city by catapulting flaming rocks over the wall (with an initial speed of 80m/s). By following the parts below, we want to know what range of angles, in degrees, you should order your troops to set the catapult? (Assume the path of the rocks is perpendicular to the wall, the ground is level with walls and you only want to hit inside the city (not the back walls)). Take the acceleration due to gravity to be 9.8 m/s2.

What is the radius equivalent to Mohrs Circle?

ENTIRE ANSWER IS WRONG

What a linear distance would be shown on a drawing if the following dimensions are drawn to the scale sizes 2”

c) Sketch the stress distribution in the section X-X

Required information Sally is making a sine bar, which is used to machine angles on parts (see the given figure). She has a 1.250-inch-thick bar that needs 90° grooves machined into it for precision ground 1.0000-inch diameter cylinders. A sine bar is used by placing different thicknesses under one of the cylinders so that the proper angle is attained. Sally wants the distance between the centers of the cylinders to be D= 5.4 inches. -D -1.0000 Ø How deep should she mill the 90° grooves so that the top of the sine block is 2 inches tall? The depth of the mill should be inches.

Dimensions are the linear or angular sizes of a component specified on the part drawing: Group of answer choices true false
