Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

**Physics: Conservation of Momentum and Energy in Collisions**

**Problem Description:**

Object A has mass \( m_A = 7 \, \text{kg} \) and initial momentum \( \vec{F}_{A,i} = \langle 19, 0, 0 \rangle \, \text{kg} \cdot \text{m/s} \), just before it strikes object B, which has mass \( m_B = 10 \, \text{kg} \). Just before the collision, object B has initial momentum \( \vec{F}_{B,i} = \langle 4, 7, 0 \rangle \, \text{kg} \cdot \text{m/s} \).

Consider a system consisting of both objects A and B. What is the total initial momentum of this system, just before the collision?

\[ \vec{F}_{sys,i} = \langle \,\,\, \,\,\, \,\,\, \rangle \, \text{kg} \cdot \text{m/s} \]

The forces that A and B exert on each other are very large but last for a very short time. If we choose a time interval from just before to just after the collision, what is the approximate value of the impulse applied to the two-object system due to forces exerted on the system by objects outside the system?

\[ \vec{F}_{ext,\Delta t} = \langle 0, 0, 0 \rangle \, \text{N} \cdot \text{s} \]

Therefore, what does the momentum principle predict that the total final momentum of the system will be, just after the collision?

\[ \vec{F}_{sys,f} = \langle \,\,\, \,\,\, \,\,\, \rangle \, \text{kg} \cdot \text{m/s} \]

Just after the collision, object A is observed to have momentum \( \vec{F}_{A,f} = \langle 15, 4, 0 \rangle \, \text{kg} \cdot \text{m/s} \). What is the momentum of object B just after the collision?

\[ \vec{F}_{B,f} = \langle \,\,\, \,\,\, \,\,\, \r

Oblique Impact To analyze an oblique impact using the conservation of momentum and coefficient of restitution. When an oblique impact occurs between two smooth particles, the particles move away from each other with velocity vectors that have unknown directions and unknown magnitudes. If the y axis is within the plane of contact and the x axis is the line of impact, the impulsive forces of deformation and restitution act only along the line of impact (the x axis). Momentum of the system is conserved along the line of impact (the x axis): ∑m(vx)1=∑m(vx)2 The coefficient of restitution, e, relates the relative-velocity components of the particles along the line of impact (the x axis): e=(vBx)2−(vAx)2(vAx)1−(vBx)1 The momenta of both particles A and B are conserved in the plane of contact (the y axis) because no impulse acts on either particle in this plane. Therefore, the y component of the velocities before and after the collisions remains unchanged: Immediately after the collision,…

A box is released from rest at the top of a ramp at time t = 0. It slides down the ramp and collides with a spring. At time t = t4, the box first comes in contact with the spring. A short while later at time t = tg, the spring reaches its maximum compression. Then the spring recoils (starts getting longer again). At time t = t42, the spring returns to its natural length and it separates from the box again. The light gray depictions of the box in the figure below labeled A and B indicate how A B Mwww far down the ramp the box would be at times ta and tg, respectively. At time t42, the box is back in location A. In the questions below, assume that you can ignore the mass of the spring. 1. As the block slides down the ramp, engages the spring, comes to a stop, and then gets pushed back up the ramp again, there are four forces acting on it: weight (w), normal force from the ramp (N), spring force (F,), and friction from the ramp (Ff). Your task is to fill in the table below. In each of the…
