25d--Mhead = 8

For m_head = 8 lb
Increasing the mass of the head to 8 lb again shifts the pattern of constraints to the left,. but leaves the number of acceptable solutions at 30 out of 81. The boundaries of the zone of allowed solutions are defined as above. The constraints imposed by v_frags > 1100 ft s^-1 coincide closely with those for PE < 0, but are less restrictive by three cases. The more restrictive PE mask is shown in all tables.

The allowed values of PE range from 110 to 600 ft-lb, very similar to the two previous ranges.

The allowed values for v_frags ranged from 420 to 920 ft s^-1, very similar to previous ranges. The mask shown below represents v_frags and PE.

Under the leftward movement relative to m_head = 7 lb, the disallowed area at the lower left has disappeared, while the disallowed area at the upper right has increased. But it still fell within the broader area of values disallowed by PE.

The speed of the lurch ranged from -9.6 to +26.6 ft s^-1. The acceptable speeds, all rearward, were 0.9–1.3 ft s^-1, the same as the previous range.
