1.14 The uniform 300-lb bar AB carries a 500-lb vertical force at A. The bar is supported by a pin at B and the 0.5-in. diameter cable CD. Find the stress in the cable. A 3ft 3ft 500 Ib

Two dimensional motion with air drag (think golf ball trajectory) is not integrable, but purely horizontal motion and purely vertical motion are separately integrable.

Initially, the system of objects shown in the figure below is held motionless. The pulley and all surfaces are frictionless. Let the force F be zero and assume that m, can move only vertically (with respect to the ground). At the instant after the system of objects is released, find each of the following. (Note: The pulley accelerates along with object M. Use the following as necessary: m₁, m₂, M, and g, where g is the magnitude of the gravitational acceleration. Do not substitute numerical values; use variables only. Take the rightward and upward directions to be positive. Indicate the direction with the sign of your answer.) (a) the tension 7 in the string T= M (b) the acceleration of m₂ am₂= (c) the acceleration of M ³M™ (d) the acceleration of m amy vertical

Imagine a book sitting on a horizontal table. One of the forces acting on a book is a normal force exerted by the table (let's call it action). What force does form the Newton's 3rd law pair (reaction)? Normal force exerted on the Earth by the book. Normal force exerted on the table by the book. Normal force exerted on the table by the Earth. Normal force exerted on the Earth by the table.
